'Requirements' in the Bible

He observed the daily requirements for sacrifices that Moses had specified for Sabbaths, new moon festivals, and the three annual celebrations -- the Feast of Unleavened Bread, the Feast of Weeks, and the Feast of Temporary Shelters.

"Your father made our burdens unbearable. Therefore you must lighten your father's requirements and his heavy burden that he placed on us, and we'll serve you."

They offer a burnt offering and fragrant incense to the Lord every morning and every evening, and they set the rows of the bread of the Presence on the ceremonially clean table. They light the lamps of the gold lampstand every evening. We are carrying out the requirements of Yahweh our God, while you have abandoned Him.

Let no one enter into the house of Yahweh except the priests and the ministering Levites. They themselves may enter, for they [are] holy, but all the people shall keep the requirements of Yahweh.
