'Consecrated' in the Bible

The men of Kiriath-jearim came and took the Ark of the LORD. They brought it to the house of Abinadab on the hill, and they consecrated his son Eleazar to care for the Ark of the LORD.

He said, "Peace, I've come to sacrifice to the LORD. Consecrate yourselves and come with me to the sacrifice." Samuel consecrated Jesse and his sons and invited them to the sacrifice.

The priest answered David: "There is no ordinary bread available; only consecrated bread, provided that the young men have kept themselves from women."

David answered the priest, saying to him, "Indeed, women were kept from us as is usual whenever I go out on a mission, and the equipment of the young men is consecrated even when it's an ordinary journey, so how much more is their equipment consecrated today?"

So the priest gave him consecrated bread because no bread was there except the Bread of the Presence that had been removed from the LORD's presence and replaced with hot bread on the day it was taken away.
