Exodus 4:18–23
Return to Egypt and the Firstborn Warning
Leave from Jethro, return with staff and family
Moses asks Jethro for leave and receives it. The LORD tells him to return; those who sought his life are dead. He takes his wife and sons and the staff of God. He is to do the wonders before Pharaoh—and God will harden Pharaoh's heart so that he will not let the people go.
Israel is named firstborn; Pharaoh's firstborn is warned
Moses is to say that Israel is the LORD's son, even his firstborn, and that the demand is 'Let my son go, that he may serve me.' Refusal will be answered against Pharaoh's firstborn.
Family language here is covenant and claim, not sentiment. Hardening and the firstborn warning are already spoken before Moses reaches Egypt. They must not be used to excuse Pharaoh's oppression or to celebrate a child's death in advance.
How this should shape us
Hold together promised wonders, announced resistance, and the moral cost already named. Do not declare an opponent beyond change as a way to justify cruelty, and do not forget that the firstborn warning concerns real households.

Where careful interpreters disagreeThe strongest options and their difficulties
Where do careful interpreters disagree?
Best judgment: Careful interpreters agree that the received text states the following: Moses receives leave from Jethro, returns with family and staff, and is told that hardening will meet the demand to release God's firstborn son Israel with a warning against Pharaoh's firstborn. They disagree over source layers, date, historical recovery, archaeology, Hebrew details, ritual development, legal use, and canonical relationship in different proportions; this study treats the final form directly while marking those alternatives as probable or uncertain rather than settled fact.
