'Believe' in the Bible

And Moses answered, and he said, "And if they do not believe me and they do not listen to my voice, but they say, 'Yahweh did not appear to you?'"

"so that they may believe that Yahweh, the God of their ancestors, appeared to you, the God of Abraham, the God of Isaac, and the God of Jacob."

"{And} if they do not believe you and they will not listen to the voice of the former sign, [then] they will believe the voice of the latter sign.

{And} if they also do not believe the second of these signs and they will not listen to your voice, [then] you must take water from the Nile and pour [it] onto the dry ground, and the water that you take from the Nile will become blood on the dry ground."
