Urim
In Numbers 27:21 the Lord commands Moses to command Joshua, Israel's new leader, to inquire of the Urim. I looked in the People's Bible but there was no explanation there. I googled it but felt a bit unsure about trusting what I would find there, so I turned to WELS.net I would appreciate having more information about it. Thank you.
I am afraid I will not be able to shed much light on the subject. Exodus 28:30 includes God’s instruction to Moses of fastening the Urim and Thummin to the breastpiece of the high priest so that the high priest, Aaron, “will always bear the means of making decisions for the Israelites over his heart before the LORD.”
What we do not know is how the Urim “worked” in enabling the high priest to receive information from God. Because “Urim” is similar to the Hebrew word for “lights,” some people have thought that they were lights or reflections in the stones of the high priest’s breastpiece. The reality is that the Urim remain shrouded in mystery to us today.
