He said:"Shall I seek for you an ilah (a god) other than Allah, while He has given you superiority over the nations."And (remember) when We rescued you from Fir`awn's people, who were afflicting you with the worst torment, killing your sons and letting your women live. And in that was a great trial from your Lord.Musa reminded the Children of Israel of Allah's blessings, such as saving them from Fir`awn, his tyranny and the humiliation and disgrace they suffered. He reminded them of the glory and revenge against their enemy, when they watched them suffering in disgrace, destroyed by drowning and meeting utter demise. We mentioned this subject in the Tafsir of Surah Al-Baqarah
