verses 6-11
When Jethro announced his arrival to Moses (“he said,” sc., through a messenger), he received his father-in-law with the honour due to his rank; and when he had conducted him to his tent, he related to him all the leading events connected with the departure from Egypt, and all the troubles they had met with on the way, and how Jehovah had delivered them out of them all. Jethro rejoiced at this, and broke out in praise to Jehovah, declaring that Jehovah was greater than all gods, i.e., that He had shown Himself to be exalted above all gods, for God is great in the eyes of men only when He makes known His greatness through the display of His omnipotence. He then gave a practical expression to his praise by a burnt-offering and slain-offering, which he presented to God. The second כּי in Exo 18:11 is only an emphatic repetition of the first, and אשׁר בּדּבר is not dependent upon ידעתּי, but upon גּדול nopu tub, or upon הגדּיל understood, which is to be supplied in thought after the second כּי: “That He has proved Himself great by the affair in which they (the Egyptians) dealt proudly against them (the Israelites).” Compare Neh 9:10, from which it is evident, that to refer these words to the destruction of Pharaoh and his army in the Red Sea as a punishment for their attempt to destroy the Israelites in the water (Exo 1:22) is too contracted an interpretation; and that they rather relate to all the measures adopted by the Egyptians for the oppression and detention of the Israelites, and signify that Jehovah had shown Himself great above all gods by all the plagues inflicted upon Egypt down to the destruction of Pharaoh and his army in the Red Sea.
Verse 12
The sacrifices, which Jethro offered to God, were applied to a sacrificial meal, in which Moses joined, as well as Aaron and all the elders.
