'Statute' in the Bible
Then he cried to Yahweh. Yahweh showed him a tree, and he threw it into the waters, and the waters were made sweet. There he made a statute and an ordinance for them, and there he tested them;
In the Tent of Meeting, outside the veil which is before the testimony, Aaron and his sons shall keep it in order from evening to morning before Yahweh: it shall be a statute forever throughout their generations on the behalf of the children of Israel.
They shall be on Aaron, and on his sons, when they go in to the Tent of Meeting, or when they come near to the altar to minister in the holy place; that they don't bear iniquity, and die: it shall be a statute forever to him and to his descendants after him.
You shall clothe them with belts, Aaron and his sons, and bind headbands on them: and they shall have the priesthood by a perpetual statute: and you shall consecrate Aaron and his sons.
So they shall wash their hands and their feet, that they not die: and it shall be a statute forever to them, even to him and to his descendants throughout their generations."
