Deuteronomy 13:3

"And thou shalt remember all the way which the LORD thy God led thee these forty years in the wilderness, to humble thee, and to prove thee, to know what was in thine heart, whether thou wouldest keep his commandments, or no."

"For there must be also heresies among you, that they which are approved may be made manifest among you."

"For thou, O God, hast proved us: thou hast tried us, as silver is tried."

"Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world."

"And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might."

"And for this cause God shall send them strong delusion, that they should believe a lie:"

"And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live."

"For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect."

"To the law and to the testimony: if they speak not according to this word, it is because there is no light in them. no...: Heb. no morning"

"Thou calledst in trouble, and I delivered thee; I answered thee in the secret place of thunder: I proved thee at the waters of Meribah. Selah."
