Genesis 1-8 provides the inspired record of the events from Creation to the Flood. Genesis 4 records the first instance of a human who engaged in worship that God rejected (Gen. 4:3-7).
We also have a record in Genesis 4 of two instances of two people who originated certain activities:
Genesis 4:20 And Adah bare Jabal: he was the father of such as dwell in tents, and of such as have cattle.
Genesis 4:21 And his brother’s name was Jubal: he was the father of all such as handle the harp and organ.
It’s noteworthy that Scripture does not provide us with any information in Genesis 4-8 about false worship involving idolatry prior to the Flood. In fact, Scripture does not give us any specific information about when humans first made idols and worshiped them.
Considering the information that has been given to us in Genesis 4 about Jabal and Jubal both originating certain things/practices/activities, it is puzzling to me that the Spirit saw fit to give us that information instead of giving us information about when humans first made objects to use in idolatrous worship.
I wonder why God has chosen to give us the revelation that He did in Genesis 4:20-21, but He has not chosen to give us information about the beginnings of idolatrous worship.
