From where did the gold come from to make the calf idol?
Answer: from the gold rings that were on the ears of the Israelites’ wives, sons, and daughters (Exodus 32:2)

I did find it intriguing to read Exodus and watch the Israelite’s journey in knowing more about God. One of the characteristics that I found interesting was describing God as a jealous God who wanted to be worshiped above all else. In my personal view of God I do not often think about the jealousy of God. In Exodus it was a very serious offense to take lightly the holiness and reverence of God. Even though mentally I know God should be number one, it would probably be wise to take more seriously and intentionally the fact that God so desires to have this type of relationship with us that he is jealous for our worship.
