Moses and Aaron
Exodus 4: 27-31
Moses explains God's words to Aaron
27 And the Lord said to Aaron: Go into the desert to meet Moses. And he went forth to meet him in the mountain of God, and kissed him. 28 And Moses told Aaron all the words of the Lord, by which he had sent him, and the signs that he had commanded.
They assemble the people of Israel
29 And they came together, and they assembled all the ancients of the children of Israel. 30 And Aaron spoke all the words which the Lord had said to Moses: and he wrought the signs before the people. 31 And the people believed. And they heard that the Lord had visited the children of Israel, and that he had looked upon their affliction: and falling down they adored.
