'On the Sabbath' in the Bible

that I may build a house for the name of the LORD my God, to consecrate it to him to burn sweet odours and to set shewbread before him perpetually, and for burnt sacrifices morning and evening, and on the Sabbath days, and the first day of every new moon, and in the solemn feasts of the LORD our God, so to continue ever in Israel.

And the king gave a portion of his substance for burnt offerings at morning and even, and for burnt offerings on the Sabbath days and new moons and other solemn feasts, according as it is written in the law of the LORD.
