'Ordinance Forever' in the Bible

"And it shall be an ordinance forever unto you. And even in the tenth day of the seventh month, ye shall humble your souls and shall do no work at all: whether it be one of yourselves or a stranger that sojourneth among you,

It shall be a Sabbath of rest unto you, and ye shall humble your souls, and it shall be an ordinance forever.

And let them no more offer their offerings unto devils, after whom they go an whoring. And this shall be an ordinance forever unto you throughout your generations.'
