For... — The mystery of birth regarded as one of the greatest mysteries (see Ecclesiastes 11:5), is a proof of God’s omniscience.
Possessed. — The context seems to require formed, fashioned, as, according to Gesenius, in Deuteronomy 32:6, (Authorised Version “bought”) (Comp. Genesis 14:19, where maker should be read for possessor.)
For “reins” see Psalms 16:7.
Covered me. — Most critics render here didst weave me. (Comp. Job 10:11.) But the usual sense of the word cover or protect, suits equally well. The prime thought is that every birth is a divine creation.
