﴿ ثُمَّ عَفَوْنَا عَنكُم مِّنۢ بَعْدِ ذَٰلِكَ لَعَلَّكُمْ تَشْكُرُونَ ﴾

“yet, even after that, We blotted out this your sin, so that you might have cause to be grateful.”

(Then, even after that), after you worshipped the calf, (We pardoned you), left you alone and did not exterminate you (in order that ye might give thanks), so that you might give thanks to Us for pardoning you.
