Cast thy burden upon the LORD, and he shall sustain thee: he shall never suffer the righteous to be moved.
Ver. 22. Cast thy burden upon the Lord] Dare tuum, vel donum tuum, that is, whatsoever thou wouldest have the Lord bestow upon thee, cast it first by faith upon him in prayer, Agedum igitur animula men cur te diutius excrucias? (Beza); even all thy cares, businesses, travails, and troubles. This David speaketh first to himself, and then to others. R. Solomon maketh this God's answer to David's prayers, Spiritus sanctus sic respondit, saith he.
And he shall sustain thee] Or, victual thee, nourish thee as a foster father; thou shalt have thy σιτομετριον, thy demensum, thy due allowance: as Joseph did his father and brethren, chepi tappam, according to the mouths of their little ones, Genesis 47:12; as Barzillai at this time nourished David at Mahanaim, 2 Samuel 17:27; 2 Samuel 19:32 .
He shall never suffer the righteous to be moved] Or if moved, yet not greatly moved, Psalms 62:2, nor removed, He will establish the just, Psalms 7:9 .
