הלכה אויף דברים 6:16

A prophet of whom another prophet testified that he is a prophet, behold, he is an established prophet and he needs no further test; for, behold, Moses our Master vouched for Joshua and all Israel believed in him before he ever delivered a token, so must it be throughout the generations. A prophet whose prophecy had already been proclaimed, and whose words were believed time after time, or if another prophet gave testimony concerning him, and he continued to follow the paths of prophecy, must not be looked upon with suspicious thoughts, or question the truth of his prophecy. And it is forbidden to test him more than necessary, or go on testing him forever for, it is said: "Ye shall not try the Lord your God, as ye tried Him in Massah" (Deut. 6.16), when they said: "Is the Lord among us, or not" (Ex. 17.7). But, since a prophet is proclaimed they should believe and know that God is among them, and not suspect nor whisper behind his back, as it is said concerning the subject: "Yet shall they know that there hath been a prophet among them" (Eze.2.5).

Not to profane the name of the Holy One, blessed be He, as it is said, “Ye shall not profane My holy name” (Lev. 22:32).

Not to put the word of God to the test, as it is said, “Ye shall not tempt the Lord, your God” (Deut. 6:16).
