Parallel
Exodus 32:30
Brenton's English Septuagint · Berean Standard Bible
And it came to pass after the morrow [had begun], that Moses said to the people, Ye have sinned a great sin; and now I will go up to God, that I may make atonement for your sin.
The next day Moses said to the people, “You have committed a great sin. Now I will go up to the LORD; perhaps I can make atonement for your sin.”
