Exodus 4:27-31

The LORD said to Aaron, “Go into the wilderness to meet Moses.” So he went and met him at the mountain of God (Sinai) and kissed him. Moses told Aaron all the words of the LORD with which He had sent him, and all the signs that He had commanded him to do. Then Moses and Aaron went [into Egypt] and assembled all the elders of the Israelites; and Aaron said all the words which the LORD had spoken to Moses. Then Moses performed the signs [given to him by God] before the people. So the people believed; and when they heard that the LORD was concerned about the Israelites and that He had looked [with compassion] on their suffering, then they bowed their heads and worshiped [the LORD].
