The Ten Commandment Lessons

The lessons God gave the Israelites after the Ten Commandments changed their lives. I am not sure, but were the Ten Commandments given to make the Israelites’ lives hard or to warm them of dangers and to show them the safe ways to go in? God also made it difficult for the Israelites to live new life. In (Deuteronomy 6 verses 6-9), I think God forced the Israelite parents and adults to must talk with the children about God’s laws. The Israelites must write words on doorposts and on gates. If the children did break the laws, who would God punish, the children, the parents, or even all the Israelites? The chaotic narrative of the transmission of the Ten Commandments is complicated. Who actually heard and saw God? Why would God want to speak to Moses, but intended the Israelites to hear the words of laws? Basically all of this seemed ambiguous in the reading.
