Jeremiah 1:18
For, behold, I have made thee this day a defenced city, and an iron pillar, and brasen walls against the whole land, against the kings of Judah, against the princes thereof, against the priests thereof, and against the people of the land.

for He has shown me His loving devotion
The term "loving devotion" is often translated from the Hebrew word "chesed," which encompasses God's steadfast love, mercy, and faithfulness. This concept is central to the Old Testament, highlighting God's unwavering commitment to His covenant with Israel. In the context of Psalm 31, David acknowledges God's personal intervention and care in his life, which is a recurring theme in his psalms. This loving devotion is also a foreshadowing of the New Testament revelation of God's love through Jesus Christ, as seen in John 3:16.

in a city under siege
The imagery of a city under siege evokes a situation of extreme distress and danger. Historically, cities in ancient Israel, such as Jerusalem, faced sieges from various enemies, including the Assyrians and Babylonians. This phrase may reflect a specific historical event in David's life or serve as a metaphor for personal trials and adversities. Theologically, it underscores God's protection and deliverance in times of crisis, as seen in other biblical accounts like the siege of Jerusalem in 2 Kings 19, where God miraculously delivered the city from the Assyrian army. This also points to the ultimate deliverance found in Christ, who provides refuge and salvation for believers amidst spiritual battles.

• David opens with praise. He is not waiting for circumstances to improve; he blesses the LORD right in the middle of crisis (Psalm 34:1; 1 Thessalonians 5:18).

• The focus is on the covenant name “LORD,” reminding us that the God who spoke to Moses at the burning bush is personally involved (Exodus 3:14).

• Praise anchors the heart when everything else shakes (Psalm 18:46; Habakkuk 3:17-18).

• David looks back at concrete evidence of God’s help, not vague optimism (Psalm 66:16).

• Testimony fuels trust: yesterday’s deliverance gives courage for today’s battle (2 Corinthians 1:10; Revelation 12:11).

• By using “me,” David personalizes God’s intervention; the Almighty cares for individuals (Psalm 40:1-3; Luke 12:6-7).

• The phrase points to God’s steadfast, covenant love—unyielding, undefeatable (Psalm 136; Lamentations 3:22-23).

• Loving devotion combines affection and loyalty: He feels for His people and acts for them (Deuteronomy 7:9; Romans 8:38-39).

• In Christ we see this devotion perfected, as He lays down His life for us (John 15:13; 1 John 4:10).

• The setting is extreme pressure: walls surrounded, supplies cut off, hope fading (2 Kings 6:24-27).

• God’s love is not hindered by locked gates or enemy armies (Psalm 46:4-7).

• When believers feel hemmed in—financially, relationally, culturally—this verse assures us that divine help reaches through every blockade (2 Corinthians 4:8-9; Hebrews 13:5-6).

Psalm 31:21 celebrates a God who deserves praise because He steps into the tightest corners of life with steadfast, personal love. David’s experience becomes ours: even when besieged, we bless the LORD, recount His past faithfulness, rely on His unwavering devotion, and rest in the certainty that no siege can keep Him out.

In a strong city.--Some see a reference to David's adventures at Ziklag or Keilah; others to Jeremiah's in Jerusalem (Jeremiah 38). It is, however, better to regard it merely as a general image of the Divine protection.
