'Hand' in the Bible

There is nothing better for a man than to eat and drink and assure himself that there is good in his labor. Even this, I have seen, is from the hand of God.

For when those riches are lost in bad investments and he becomes the father of a son, then there is nothing in his hand [for the support of the child].

As he came naked from his mother’s womb, so he will return as he came; and he will take away nothing from all his labor that he can carry in his hand.

It is good that you take hold of one thing (righteousness) and also not let go of the other (wisdom); for the one who fears and worships God [with awe-filled reverence] will come forth with both of them.

Whatever your hand finds to do, do it with all your might; for there is no activity or planning or knowledge or wisdom in Sheol (the nether world, the place of the dead) where you are going.

A wise man’s heart turns him toward the right [which is the way of blessing], but a fool’s heart turns him toward the left [which is the way of condemnation].
