“And when Moses went into the tent of meeting to speak with the LORD, he heard the voice speaking to him from above the mercy seat …” (v89). The Israelites had the awesome (and fearful) privilege of serving the Creator. When the chiefs of the tribes brought their gifts to dedicate the altar (v2), they were offering sincere thanks to the living God who had rescued them from Egypt. The beauties of the ancient tabernacle became holy because God’s real presence and His voice were among them.
“The voice … spoke to him” (v89). Like Moses, we can experience God’s presence and know Him personally, because we are part of His “treasured possession” in Christ (Ex 19:5).
