1 Samuel 6:6
King James Version
“Wherefore then do ye harden your hearts, as the Egyptians and Pharaoh hardened their hearts? when he had wrought wonderfully among them, did they not let the people go, and they departed?”
Context
3And they said, If ye send away the ark of the God of Israel, send it not empty; but in any wise return him a trespass offering: then ye shall be healed, and it shall be known to you why his hand is not removed from you.
4Then said they, What the trespass offering which we shall return to him? They answered, Five golden emerods, and five golden mice, the number of the lords of the Philistines: for one plague was on you all, and on your lords.
5Wherefore ye shall make images of your emerods, and images of your mice that mar the land; and ye shall give glory unto the God of Israel: peradventure he will lighten his hand from off you, and from off your gods, and from off your land.
6Wherefore then do ye harden your hearts, as the Egyptians and Pharaoh hardened their hearts? when he had wrought wonderfully among them, did they not let the people go, and they departed?
7Now therefore make a new cart, and take two milch kine, on which there hath come no yoke, and tie the kine to the cart, and bring their calves home from them:
8And take the ark of the LORD, and lay it upon the cart; and put the jewels of gold, which ye return him a trespass offering, in a coffer by the side thereof; and send it away, that it may go.
9And see, if it goeth up by the way of his own coast to Beth-shemesh, he hath done us this great evil: but if not, then we shall know that not his hand smote us; it a chance happened to us.
