'Statute Forever' in the Bible

in the tabernacle of the congregation, outside the veil which is before the testimony. Aaron and his sons shall order it from evening to morning before Jehovah. It shall be a statute forever to their generations on behalf of the sons of Israel.

And they shall be upon Aaron, and upon his sons, when they come in to the tabernacle of the congregation, or when they come near the altar to minister in the holy place; so that they do not bear iniquity, and die. It shall be a statute forever to him and his seed after him.

And it shall be Aaron's and his sons' by a statute forever from the sons of Israel. For it is a heave offering. And it shall be a heave offering from the sons of Israel of the sacrifices of their peace offerings, even their heave offering to Jehovah.

they shall wash their hands and their feet, so that they do not die. And it shall be a statute forever to them, to him and to his seed throughout their generations.
