Genesis 35:1

Arise go to Bethel — Here God minds Jacob of his vow at Beth — el, and sends him thither to perform it, Jacob had said in the day of his distress, If I come again in peace, this stone shall be God's house, Genesis 28:22. God had performed his part, had given Jacob more than bread to eat, and raiment to put on; but it should seem he had forgotten his vow, or, at least, deferred the performance of it. And dwell there — That is, Not only go himself, but take his family with him, that they might join with him in his devotions. Put away the strange Gods — Strange God's in Jacob's family! Could such a family, that was taught the knowledge of the Lord, admit them? Could such a master, to whom God had appeared twice, and oftner, connive at them? And be clean, and change your garments — These were ceremonies signifying the purification and change of the heart.
