'Set apart' in the Bible

Then Moses set apart three cities beyond the Jordan toward the sunrising;

At that time Jehovah set apart the tribe of Levi, to bear the ark of the covenant of Jehovah, to stand before Jehovah to minister unto him, and to bless in his name, unto this day.

thou shalt set apart three cities for thee in the midst of thy land, which Jehovah thy God giveth thee to possess it.

Wherefore I command thee, saying, Thou shalt set apart three cities for thee.
