30 The next day Moses said to the people, “You have committed a very serious sin, but now I will go up to the Lord—perhaps I can make atonement on behalf of your sin.” 31 So Moses returned to the Lord and said, “Alas, this people has committed a very serious sin, and they have made for themselves gods of gold. 32 But now, if you will forgive their sin…, but if not, wipe me out from your book that you have written.” 33 The Lord said to Moses, “Whoever has sinned against me—that person I will wipe out of my book. 34 So now go, lead the people to the place I have spoken to you about. See, my angel will go before you. But on the day that I punish, I will indeed punish them for their sin.” 35 And the Lord sent a plague on the people because they had made the calf—the one Aaron made.

2 Wake up then, and strengthen what remains that was about to die, because I have not found your deeds complete in the sight of my God. 3 Therefore, remember what you received and heard, and obey it, and repent. If you do not wake up, I will come like a thief, and you will never know at what hour I will come against you. 4 But you have a few individuals in Sardis who have not stained their clothes, and they will walk with me dressed in white because they are worthy. 5 The one who conquers will be dressed like them in white clothing, and I will never erase his name from the book of life, but will declare his name before my Father and before his angels. 6 The one who has an ear had better hear what the Spirit says to the churches.’
