'Reason' in the Bible

The reason is so that the sons of Israel may bring their sacrifices which they were sacrificing in the open field, that they may bring them in to the Lord, at the doorway of the tent of meeting to the priest, and sacrifice them as sacrifices of peace offerings to the Lord.

For the life of the flesh is in the blood, and I have given it to you on the altar to make atonement for your souls; for it is the blood by reason of the life that makes atonement.’
