Every time the penalty fell on them, they said: "O Moses! on your behalf call on thy Lord in virtue of his promise to thee: If thou wilt remove the penalty from us, we shall truly believe in thee, and we shall send away the Children of Israel with thee."
And when the punishment descended upon them, they said, "O Moses, invoke for us your Lord by what He has promised you. If you [can] remove the punishment from us, we will surely believe you, and we will send with you the Children of Israel."
