The cases of Pharaoh and Abimelech only confirm the remarks we have made. Moreover, in the parallel part of the passage, Jehovah is used in both cases. Jehovah plagued Pharaoh with great plagues. Jehovah had fast closed up the wombs of the house of Abimelech. Only there is added in Abimelech's case, God having known Abimelech's integrity in the matter, that He (Elohim) warned Abimelech in a dream. Now here Jehovah the God of Israel would have been quite out of place; for Abimelech was a Philistine, and Abraham already distinctively called. Yet, as a gracious God in nature and character, Elohim could chastise Abimelech temporarily for his error, and warn him, though He would preserve the integrity of the family He had chosen.
Here let me remark, that undoubtedly Abraham was to blame.
In the day when God judges the secrets of men's hearts, all this will have its place between God and Abraham; but in His government of the world, all having fallen into idolatry, God was showing His special care over one called out in grace to bear His name, and walk under His protection. Hence that special care of him and his descendants, till there was no remedy, because they respected the name of Jehovah less than a heathen, as was shown in Zedekiah's conduct with Nebuchadnezzar. He that touched them, Jehovah's called ones, touched Jehovah Himself, who declared He would protect them as ΕΙ-Shaddai, the Almighty, such a one touched the apple of His own eye. Jehovah's power as Almighty had to be made good against the apostate and guilty heathen, for the sustaining the faith of His called ones, and the knowledge that there was a God of the earth.
But the statement, that these names are contrasted in Abraham's case with Pharaoh and Abimelech, is unfounded. There is no divine warning to Pharaoh; and Jehovah's care of Abraham, in judging each, is related under the same title Jehovah.
