'Consecrate' in the Bible

"At this time tomorrow I will send to you a man from the land of Benjamin. You must consecrate him as a leader over my people Israel. He will save my people from the hand of the Philistines. For I have looked with favor on my people. Their cry has reached me!"

He replied, "Yes, in peace. I have come to sacrifice to the Lord. Consecrate yourselves and come with me to the sacrifice." So he consecrated Jesse and his sons and invited them to the sacrifice.
