'I Will Be with You' in the Bible

No man will [be able to] stand before you [to oppose you] as long as you live. Just as I was [present] with Moses, so will I be with you; I will not fail you or abandon you.

The Lord said to Joshua, “This day I will begin to magnify and exalt you in the sight of all Israel, so that they may know that just as I was with Moses, I will [also] be with you.
