The 400 years of silence, also called the intertestamental period, refers to the time between the Old Testament and New Testament, during which, so far as we know, God did not speak—no Scripture was written. The 400 years of silence began with the warning that closed the Old Testament: “Behold, I am going to send you Elijah the prophet before the coming of the great and terrible day of the LORD. He will restore the hearts of the fathers to their children and the hearts of the children to their fathers, so that I will not come and smite the land with a curse" (Malachi 4:5-6) and ended with the coming of John the Baptist, the Messiah’s forerunner.
