'In Me' in the Bible

But so it was that there were, certain men who had become unclean by a dead person, and could not keep the passover on that day, - therefore came they near before Moses and before Aaron on that day.

Then said Yahweh unto How long! must this people, despise me? And how long can they not believe in me. in view of all the signs which I have done in their midst?

and rose up before Moses, with certain men of the sons of Israel, two hundred and fifty, - princes of assembly, called to the stated meeting, men of renown;

Then said Yahweh unto Moses and unto Aaron, Because ye believed not in me, to hallow me in the eyes of the sons of Israel, therefore, shall ye not bring in this convocation into the land which I have given unto them.
