'Reason' in the Bible

The priest shall offer one for a sin offering, and the other for a burnt offering, and make atonement for him, because he sinned by reason of the dead, and shall make his head holy that same day.

"Say to the children of Israel, 'If any man of you or of your generations is unclean by reason of a dead body, or is on a journey far away, he shall still keep the Passover to Yahweh.

Yahweh spoke to Aaron, "I, behold, I have given you the command of my wave offerings, even all the holy things of the children of Israel; to you have I given them by reason of the anointing, and to your sons, as a portion forever.

You shall bear no sin by reason of it, when you have heaved from it its best: and you shall not profane the holy things of the children of Israel, that you not die.'"
