Exodus Chapter 23

23:7-9
Keep thee far from a false matter; and the innocent and righteous slay thou not: for I will not justify the wicked.
And thou shalt take no gift: for the gift blindeth the wise, and perverteth the words of the righteous.
Also thou shalt not oppress a stranger: for ye know the heart of a stranger, seeing ye were strangers in the land of Egypt.

23:20-21
Behold, I send an Angel before thee, to keep thee in the way, and to bring thee into the place which I have prepared.
Beware of him, and obey his voice, provoke him not; for he will not pardon your transgressions: for my name is in him.

23:29-31
I will not drive them out from before thee in one year; lest the land become desolate, and the beast of the field multiply against thee.
By little and little I will drive them out from before thee, until thou be increased, and inherit the land.
And I will set thy bounds from the Red sea even unto the sea of the Philistines, and from the desert unto the river; for I will deliver the inhabitants of the land into your hand; and thou shalt drive them out before thee.
