Psalm 18:2-4, 47-51 and Exodus 22:20-26

Psalm 18:2-4, 47-51
2 I will love you, O Lord my strength.
3 The Lord is my firmament, my refuge, and my liberator. My God is my helper, and I hope in him: my protector, and the horn of my salvation, and my support.
4 Praising, I will call upon the Lord. And I will be saved from my enemies.
47 The Lord lives, and blessed is my God, and may the God of my salvation be exalted:
48 O God, who vindicates me and who subdues the people under me, my liberator from my enraged enemies.
49 And you will exalt me above those who rise up against me. From the iniquitous man, you will rescue me.
50 Because of this, O Lord, I will confess to you among the nations, and I will compose a psalm to your name:
51 magnifying the salvation of his king, and showing mercy to David, his Christ, and to his offspring, even for all time.
Exodus 22:20-26
20 Whoever immolates to gods, other than to the Lord, shall be killed.
21 You shall not harass the newcomer, nor shall you afflict him. For you yourselves were once newcomers in the land of Egypt.
22 You shall not harm a widow or an orphan.
23 If you hurt them, they will cry out to me, and I will hear their cry.
24 And my fury will be enraged, and I will strike you down with the sword. And your wives will become widows, and your sons will become orphans.
25 If you lend money to the poor of my people who live among you, you shall not coerce them like a collector, nor oppress them with usury.
26 If you take a garment from your neighbor as a pledge, you shall return it to him again before the setting of the sun.
