Why the Lord said, For as much as this people draw near me with their mouth, and with their lips do honor me, but have removed their heart far from me, and their fear toward me is taught by the precept of men:
forasmuch
Isaiah 10:6 I will send him against an hypocritical nation, and against the people of my wrath will I give him a charge, to take the spoil, and to take the prey, and to tread them down like the mire of the streets.
Isaiah 48:1,2 Hear ye this, O house of Jacob, which are called by the name of Israel, and are come forth out of the waters of Judah, which swear by the name of the LORD, and make mention of the God of Israel, but not in truth, nor in righteousness…
Isaiah 58:2,3 Yet they seek me daily, and delight to know my ways, as a nation that did righteousness, and forsook not the ordinance of their God: they ask of me the ordinances of justice; they take delight in approaching to God…
their fear
2 Chronicles 29:1 Hezekiah began to reign when he was five and twenty years old, and he reigned nine and twenty years in Jerusalem. And his mother's name was Abijah, the daughter of Zechariah.
2 Chronicles 30:1 And Hezekiah sent to all Israel and Judah, and wrote letters also to Ephraim and Manasseh, that they should come to the house of the LORD at Jerusalem, to keep the passover unto the LORD God of Israel.
2 Chronicles 31:1 Now when all this was finished, all Israel that were present went out to the cities of Judah, and brake the images in pieces, and cut down the groves, and threw down the high places and the altars out of all Judah and Benjamin, in Ephraim also and Manasseh, until they had utterly destroyed them all. Then all the children of Israel returned, every man to his possession, into their own cities.
These people draw near to Me with their mouths and honor Me with their lips:
This highlights the superficiality of the people's worship. They perform religious rituals and speak words of devotion, but it is not genuine. This reflects a common theme in the Old Testament where God desires sincere worship from the heart rather than mere external compliance (see 1 Samuel 15:22 and Hosea 6:6). Jesus later quotes this passage in Matthew 15:8-9 and Mark 7:6-7, applying it to the Pharisees, showing its enduring relevance.
But their hearts are far from Me:
The heart, in biblical terms, represents the center of one's being, including emotions, will, and intellect. This phrase indicates a disconnect between outward actions and inner reality. The people of Israel were engaging in religious practices without true devotion or love for God. This is a recurring issue in Israel's history, where external religiosity often masked internal rebellion (see Ezekiel 33:31).
Their worship of Me is but rules taught by men:
This critique points to the human traditions and commandments that had supplanted genuine worship. It suggests that the people were more focused on following human traditions than on understanding and obeying God's commandments. This is a warning against legalism and the danger of elevating human traditions above divine revelation. Jesus' use of this passage in the Gospels criticizes the Pharisees for similar practices, emphasizing the need for worship that is rooted in truth and spirit (John 4:24).
• Isaiah pauses to remind us that these words do not originate with a prophet’s opinion but with the covenant-keeping LORD Himself (cf. Isaiah 1:18–20; Jeremiah 7:13).
• Because God is speaking, the statement that follows carries absolute authority and exposes the true spiritual condition of Judah.
• Outwardly, Judah still attended Temple rituals, recited prayers, and offered sacrifices—activities God had prescribed (Exodus 23:14–17).
• Yet their verbal closeness was only ceremonial; it echoed earlier warnings about shallow words (Jeremiah 12:2; Ezekiel 33:31).
• Jesus later cites this line when confronting the Pharisees’ empty speech (Matthew 15:8).
• “Honor” here is lip-service respect: words that sound pious but lack substance (Psalm 78:36; Titus 1:16).
• Such lip-honor can fool observers, but never the Lord who hears every word and weighs every motive (Psalm 139:4).
• The heart—seat of will, affection, and thought—was disengaged; rituals continued while relationship died (Deuteronomy 6:5; 1 Samuel 16:7).
• God desires wholehearted devotion, not merely correct vocabulary (Proverbs 4:23; Jeremiah 17:10).
• Jesus applies this diagnosis to first-century legalists, proving the principle transcends time (Mark 7:6).
• When human tradition eclipses divine revelation, worship degenerates into man-made routines (Colossians 2:22–23).
• Judah had multiplied regulations (Isaiah 1:11–15), confusing form with faith; later, Pharisaic tradition would repeat the error (Matthew 15:9).
• God rejects worship that separates obedience from compassion and justice (Micah 6:6–8; Amos 5:21–24).
Isaiah 29:13 exposes the danger of religious performance divorced from genuine devotion. God sees through eloquent prayers and meticulous rituals when the heart is elsewhere. He calls His people back to authentic, Scripture-shaped worship—where lips and life align, traditions serve truth, and the heart stays close to the Lord who speaks.
(13) Wherefore the Lord said . . .--We pass from the effect to the cause. The blind stupor was the outcome of a long hypocrisy. Lip-homage and an estranged heart had been the notes of the religious life of Israel, and they could bear no other fruit.Their fear toward me . . .--The words point to what we may call an anticipated Pharisaism. Side by side with the great commandments of the Law and with the incisive teaching of the prophets there was growing up even then a traditional system of ethics and religion, based upon wrong principles, ending in a dishonest casuistry and a formal devotion. Commentaries even then were darkening counsel by words without knowledge, as they did in the Mishna and the Gemara of the later days of Judaism (Matthew 15:3; Mark 7:6).
Verse 13. - Wherefore the Lord said; rather, moreover the Lord said. This people draw near me with their mouth. Samaria had been punished for open idolatry and flagrant neglect of Jehovah (2 Kings 17:7-17). Jerusalem had not gone these lengths. She still, in profession, clung to the worship of Jehovah, and had even recently accepted a purification of religion at the hand of Hezekiah, who had "removed the high places," and cut down the groves, and broken in pieces the brazen serpent," because the people burnt incense to it (2 Kings 18:4). But her religion was a mere lip-service, which God detested - it was outward, formal, hypocritical (comp. Isaiah 1:11-17). Jerusalem, therefore, no less than Samaria, deserved and would receive a severe chastisement. But have removed their heart far from me. Here lies the gist of the charge. It was not that there was too much outward religion, but that there was no inward religion corresponding to it. Lip-service without inward religion is a mockery, though it is not always felt as such. Their fear toward me is taught by the precept of men. Mr. Cheyne conjectures that ritual books had been already published by the authority of the priests, and that these were followed, on account of the human authority which had issued them, without any reference to the Law. Thus ritual obedience became mere obedience to "the precept of men."
