'Set apart' in the Bible

But on that day I will separate and set apart the land of Goshen, where My people are living, so that no swarms of insects will be there, so that you may know [without any doubt] and acknowledge that I, the Lord, am in the midst of the earth.

“Sanctify to Me [that is, set apart for My purpose] every firstborn, the first offspring of every womb among the children of Israel, both of man and of animal; it is Mine.”

you shall set apart and dedicate to the Lord all that first opens the womb. All the firstborn males of your livestock shall be the Lord’s.

and you shall be to Me a kingdom of priests and a holy nation [set apart for My purpose].’ These are the words that you shall speak to the Israelites.”

Also have the priests who approach the Lord consecrate (sanctify, set apart) themselves [for My sacred purpose], or else the Lord will break forth [in judgment] against them [and destroy them].”

You are to make sacred garments [official clothing reserved for holy services] for Aaron your brother, for honor and for beauty (ornamentation).

You shall consecrate the waved breast offering [of the ram] used in the ordination and the waved thigh offering of the priests’ portion, since it is [a contribution] for Aaron and for his sons.

“You shall take the ram of the ordination and boil its meat in a holy place.

They shall eat those things by which atonement was made at their ordination and consecration; but a layman shall not eat them, because they are holy [that is, set apart to the worship of God].

And if any of the meat of ordination or the bread remains until morning, you shall burn it in the fire; it shall not be eaten, because it is holy.

For seven days you shall make atonement for the altar [of burnt offering] and consecrate it; then the altar shall be most holy. Whatever touches the altar must be holy (set apart for God’s service).

You shall consecrate them, that they may be most holy; whatever touches them must be holy (set apart for God).

You shall anoint the altar of burnt offering and all its utensils, and consecrate the altar, and the altar shall be most holy.
