Behold, he cometh forth to meet thee— This latter part of the verse would be rendered more properly, behold, he shall come forth to meet thee: and when he shall see thee, he shall rejoice in his heart: and, perhaps, the phrase, he cometh forth to meet thee, or to thy meeting, may imply the readiness of Aaron to unite with Moses in this grand undertaking. The Almighty here gives Moses a further proof of his power, by foretelling him in what manner he would bring Aaron to him, and unite him in counsel with him.
