'Sacred' in the Bible

And they went out and preached everywhere, while the Lord worked with them, and confirmed the word by the signs that followed.][And they promptly reported all these instructions to Peter and his companions. And after that, Jesus Himself sent out through them from east to west the sacred and imperishable proclamation of eternal salvation.]

Do you not know that those who perform sacred services eat the food of the temple, and those who attend regularly to the altar have their share from the altar?

and that from childhood you have known the sacred writings which are able to give you the wisdom that leads to salvation through faith which is in Christ Jesus.

For there was a tabernacle prepared, the outer one, in which were the lampstand and the table and the sacred bread; this is called the holy place.
