'Hallow' in the Bible

And the priest shall offer the one for a sin offering, and the other for a burnt offering, and make an atonement for him, for that he sinned by the dead, and shall hallow his head that same day.

And unto the people shalt thou say, Hallow yourselves for to-morrow, and ye shall eat flesh; for ye have wept in the ears of Jehovah, saying, Who will give us flesh to eat? for it was well with us in Egypt; and Jehovah will give you flesh, and ye shall eat.

And Jehovah said to Moses and to Aaron, Because ye believed me not, to hallow me before the eyes of the children of Israel, therefore ye shall not bring this congregation into the land that I have given them.
