'Hands' in the Bible

Thus I considered all my activities which my hands had done and the labor which I had exerted, and behold all was vanity and striving after wind and there was no profit under the sun.

The fool folds his hands and consumes his own flesh.

Do not let your speech cause you to sin and do not say in the presence of the messenger of God that it was a mistake. Why should God be angry on account of your voice and destroy the work of your hands?

And I discovered more bitter than death the woman whose heart is snares and nets, whose hands are chains. One who is pleasing to God will escape from her, but the sinner will be captured by her.
