John Gill Commentary Psalms 91:12

"They shall bear thee up in their hands, Lest thou dash thy foot against a stone." — Psalms 91:12 (ASV)

They shall bear you up in their hands

Which denotes the strength and power of angels to carry the saints in their hands; their tender care of them, such as a parent or nurse have of children; the helpless condition of the people of God, who are like infants, and need to be dealt with after this manner; the condescension of angels to take such an office on them, in submission to the will of God; the constant view they have of the saints, being always in their hands, and so in sight: thus they bear them, up in life, and at death carry their souls to Abraham's bosom:

lest you dash your foot against a stone ;

lest they fall into sin, or into any calamity and distress; lest the least hurt or mischief befall them, or the least injury be done them; see (Proverbs 3:23) . The Targum interprets it of the evil concupiscence, or corruption of nature, which is like a stone; see (Ezekiel 36:26) .
