Psalms 139:5

In verse fifth some read —behind and before thou hast fashioned me; (203) but צור, tsur, often signifies to shut up, and David, there can be no doubt, means that he was surrounded on every side, and so kept in sight by God, that he could not escape in any quarter. One who finds the way blocked up turns back; but David found himself hedged in behind as well as before. The other clause of the verse has the same meaning; for those put a very forced interpretation upon it who think that it refers to God’s fashioning us, and applying his hand in the sense of an artizan to his work; nor does this suit with the context. And it is much better to understand it as asserting that God by his hand, laid as it were upon men, holds them strictly under his inspection, so that they cannot move a hair’s breadth without his knowledge. (204)
