'Sanctify' in the Bible

And unto the people thou dost say, Sanctify yourselves for to-morrow, and ye have eaten flesh (for ye have wept in the ears of Jehovah, saying, Who doth give us flesh? for we had good in Egypt) -- and Jehovah hath given to you flesh, and ye have eaten.

And Jehovah saith unto Moses, and unto Aaron, 'Because ye have not believed in Me to sanctify Me before the eyes of the sons of Israel, therefore ye do not bring in this assembly unto the land which I have given to them.'

because ye provoked My mouth in the wilderness of Zin, in the strife of the company -- to sanctify Me at the waters before their eyes;' they are waters of Meribah, in Kadesh, in the wilderness of Zin.
