Exodus Chapter 34

34:6-10
And the Lord passed by before him, and proclaimed, The Lord, The Lord God, merciful and gracious, longsuffering, and abundant in goodness and truth,
Keeping mercy for thousands, forgiving iniquity and transgression and sin, and that will by no means clear the guilty; visiting the iniquity of the fathers upon the children, and upon the children's children, unto the third and to the fourth generation.
And Moses made haste, and bowed his head toward the earth, and worshipped.
And he said, If now I have found grace in thy sight, O Lord, let my Lord, I pray thee, go among us; for it is a stiffnecked people; and pardon our iniquity and our sin, and take us for thine inheritance.
And he said, Behold, I make a covenant: before all thy people I will do marvels, such as have not been done in all the earth, nor in any nation: and all the people among which thou art shall see the work of the Lord: for it is a terrible thing that I will do with thee.

34:13-17
But ye shall destroy their altars, break their images, and cut down their groves:
For thou shalt worship no other god: for the Lord, whose name is Jealous, is a jealous God:
Lest thou make a covenant with the inhabitants of the land, and they go a-whoring after their gods, and do sacrifice unto their gods, and one call thee, and thou eat of his sacrifice;
And thou take of their daughters unto thy sons, and their daughters go a-whoring after their gods, and make thy sons go a-whoring after their gods.
Thou shalt make thee no molten gods.

34:21-22
Six days thou shalt work, but on the seventh day thou shalt rest: in earing time and in harvest thou shalt rest.
And thou shalt observe the feast of weeks, of the firstfruits of wheat harvest, and the feast of ingathering at the year's end.

34:29-30
And it came to pass, when Moses came down from mount Sinai with the two tables of testimony in Moses' hand, when he came down from the mount, that Moses wist not that the skin of his face shone while he talked with him.
And when Aaron and all the children of Israel saw Moses, behold, the skin of his face shone; and they were afraid to come nigh him.
