Most of this account is God’s ordered sacrifice of Yitskhak (Isaac). This is a disturbing command until we see that the point was to show Abraham’s deep trust in God’s promises and power to resurrect as well as to show how heart-wrenching a future act against God’s “one and only son” would be.
God’s severe instruction for dealing with someone who has dreams or receives messages that come true and who performs miracles is sobering. It was not a problem for a prophet or dreamer outside the Levitical community to perform miracles or have visions. It became a problem if that person spoke out against the Creator and Redeemer revealed in the Bible or spoke for a false god.
This is a very heavy section of scripture. God tells Moses about the people’s rebellion and calls on Moses to check on the people. God tells Moses that he is willing to take very drastic measures to punish the people and promote Moses to an even higher level.
