'Be Holy' in the Bible

And as long as the vow of his abstinence endureth, there shall no razor nor shears come upon his head, until his days be out which he fasteth unto the LORD, and he shall be holy and shall let the locks of his hair grow.

And therefore as long as his abstinence lasteth, he shall be holy unto the LORD.

and the priest shall wave them unto the LORD, which offering shall be holy unto the priest with the wavebreast and heaveshoulder: and then the abstainer may drink wine.

but that ye remember and do all my commandments and be holy unto your God:

And ye shall eat it in the most holy place: all that are males shall eat of it, for it shall be holy unto thee.
