Psalm 91 Vs. 12

Psalm 91 Vs. 12

They shall bear thee up in their hands, lest thou dash thy foot against a stone. Psm. 91:12

They shall bear... 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... 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 Prov. 3:23). The Targum interprets it of the evil concupiscence, or corruption of nature, which is like a stone (see Ezek. 36:26).
This just means that they help us in our walk through life. Many times, the nudging we feel is an angel warning us of disaster ahead. The road through life might be pretty rough, but their hands lift us above the problems, so that we can make it to the other side.

Satan, in tempting Christ, quoted Psm. 91:11-12 (Mat. 4:6), which shows that even God’s most marvelous promises can be foolishly applied.
