comprehensive promise was still further explained by the Lord (Exo 6:2-9), and Moses was instructed and authorized to carry out the divine purposes in concert with Aaron (Exo 6:10-13, Exo 6:28-30; Exo 7:1-6). The genealogy of the two messengers is then introduced into the midst of these instructions (Exo 6:14-27); and the age of Moses is given at the close (Exo 7:7). This section does not contain a different account of the calling of Moses, taken from some other source than the previous one; it rather presupposes Exo 3-5, and completes the account commenced in Exo 3 of the equipment of Moses and Aaron as the executors of the divine will with regard to Pharaoh and Israel. For the fact that the first visit paid by Moses and Aaron to Pharaoh was simply intended to bring out the attitude of Pharaoh towards the purposes of Jehovah, and to show the necessity for the great judgments of God, is distinctly expressed in the words, “Now shalt thou see what I will do to Pharaoh.” But before these judgments commenced, Jehovah announced to Moses (Exo 6:2), and through him to the people, that henceforth He would manifest Himself to them in a much more glorious manner than to the patriarchs, namely, as Jehovah; whereas to Abraham, Isaac, and Jacob, He had only appeared as El Shaddai. The words, “By My name Jehovah was I now known to them,” do not mean, however, that the patriarchs were altogether ignorant of the name Jehovah. This is obvious from the significant use of that name, which was not an unmeaning sound, but a real expression of the divine nature, and still more from the unmistakeable connection between the explanation given by God here and Gen 17:1. When the establishment of the covenant commenced, as described in Gen 15, with the institution of the covenant sign of circumcision and the promise of the birth of Isaac, Jehovah said to Abram, “I am El Shaddai, God Almighty,” and from that time forward manifested Himself to Abram and his wife as the Almighty, in the birth of Isaac, which took place apart altogether from the powers of nature, and also in the preservation, guidance, and multiplication of his seed. It was in His attribute as El Shaddai that God had revealed His nature to the patriarchs; but now He was about to reveal Himself to Israel as Jehovah, as the absolute Being working with unbounded freedom in the performance of His promises. For not only had He established His covenant with the fathers (Exo 6:4),
