Ecclesiastes 5:15

5:15 Just as he came forth from his mother's womb, naked will he return as he came,

and he will take nothing in his hand that he may carry away from his toil.

Ecclesiastes 11:5

11:5 Just as you do not know the path of the wind,

or how the bones form in the womb of a pregnant woman,

so you do not know the work of God who makes everything.
