Deuteronomy 25:17-18

Out of Egypt Which circumstance greatly aggravated their sin, that they should do thus to a people who had been long exercised with sore afflictions, to whom pity was due by the laws of nature and humanity, and for whose rescue God had in so glorious a manner appeared, which they could not be ignorant of. And he feared not God Though they feared Israel, whom they durst not look in the face, but cut them off behind, yet they feared not God, but acted a base and inhuman part, in contempt of the divine authority, and of all the miraculous interpositions of the divine providence in behalf of that chosen nation. So that while their conduct was barbarous to Israel, they set the great Jehovah at defiance.
