Psalms 33:15

33:15 He is the one who forms every human heart, 1 

and takes note of all their actions.

Psalms 66:1

Psalm 66 2 

For the music director; a song, a psalm.

66:1 Shout out praise to God, all the earth!

1 tn Heb “the one who forms together their heart[s].” “Heart” here refers to human nature, composed of intellect, emotions and will. The precise force of יָחַד (yakhad, “together”) is unclear here. The point seems to be that the Lord is the creator of every human being.

2 sn Psalm 66. The psalmist praises God because he has delivered his people from a crisis.
