'Sacred' in the Bible

how he entered the house of God, and they ate the sacred bread, which is not lawful for him or for those with him to eat, but only for the priests?

how he entered the house of God in the time of Abiathar the high priest and ate the sacred bread—which is not lawful for anyone to eat except the priests—and also gave some to his companions?”

how he entered the house of God, and took and ate the sacred bread, which is not lawful for any but the priests to eat? He even gave some to those who were with him.”

Now to Him who has power to strengthen you according to my gospel and the proclamation about Jesus Christ, according to the revelation of the mystery kept silent for long ages

and you know that from childhood you have known the sacred Scriptures, which are able to give you wisdom for salvation through faith in Christ Jesus.
