'Leave' in the Bible

I will not leave you orphans, I am coming to you.

I leave peace with you; I give my peace to you: not as the world gives do I give to you. Let not your heart be troubled, neither let it fear.

I came out from the Father and have come into the world; again, I leave the world and go to the Father.

Behold, the hour is coming, and has come, that ye shall be scattered, each to his own, and shall leave me alone; and yet I am not alone, for the Father is with me.
