An extract from John Gill's Exposition of the Bible:Yes, and the following verse ought to cause us to wonder who David was writing about:
Psalm 91:11-12 NLT - "For he will order his angels to protect you wherever you go. 12 They will hold you up with their hands so you won't even hurt your foot on a stone."
"Psalm 91.12:
They shall bear thee 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 thou dash thy 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 (Proberbs 3:23). The Targum interprets it of the evil concupiscence, or corruption of nature, which is like a stone; see ( Ezekiel 36:26)."
Psalm 91 speaks about Christ, but it is also applicable to all Christians.
