2 Samuel 9:3 shows David actively seeking to show kindness to Saul's house, fulfilling the same 'chesed' he promised in 2:6.

In 2 Samuel 9:7, David again promises kindness (chesed) to Mephibosheth for Jonathan's sake — same pattern of covenant loyalty shown here to Jabesh-gilead for burying Saul.

In 2 Samuel 10:2, David says 'I will deal kindly' (same Hebrew chesed) with Hanun, reciprocating past kindness — mirroring his promise here to reward those who honored Saul.

Psalm 57:3 echoes 'steadfast love and faithfulness' — the same Hebrew phrase David uses to describe God's character.

Proverbs 14:22 promises that those who devise good meet 'steadfast love and faithfulness' — the same phrase David invokes.

In Matthew 5:44, Jesus commands love for enemies — David's conditional kindness contrasts sharply with the radical, unconditional love Jesus teaches.

Matthew 5:7 promises mercy to the merciful, paralleling David's blessing that God will show kindness to those who show kindness.

2 Timothy 1:16-18 prays for mercy on Onesiphorus for his kindness to Paul, mirroring David's promise of reciprocal kindness.
