Exodus 23:32,33

Thou shalt make no covenant with them Thou shalt give no toleration to idol-worship, nor suffer it to be introduced into thy territories. Thou shalt make no league with them, either civil or religious. They shall not dwell in thy land Unless they renounce their idolatry, which is plainly understood; for, upon their becoming proselytes to the Jewish religion, they might dwell among them, and were called the strangers. If thou serve Thou wilt serve, this will be the fruit of thy cohabitation with them. It will be a snare unto thee Will bring great calamities upon thee, and, at last, be thy ruin, which accordingly came to pass.
