Charles Ellicott Commentary Exodus 18:8

"And Moses told his father-in-law all that Jehovah had done unto Pharaoh and to the Egyptians for Israel`s sake, all the travail that had come upon them by the way, and how Jehovah delivered them." — Exodus 18:8 (ASV)

Moses told ... All. —Jethro had only heard previously a very imperfect account of the transactions. (See Note 2 on Exodus 18:1.) Moses now told him all the particulars.
