The Women - 4:154
"We raised Mount Sinai above them, and We said to them, "Enter humbly through the gate."We said to them, "Do not transgress the prohibition of Saturday"; and We took from them a firm promise."
Our Lord's promise to the Children of Israel:
The Table Spread/5:12
"Allah had taken a promise from the Children of Israel and We sent twelve leaders from among them. Allah said: "I am with you if you observe the prayer, pay the zakat, believe in My messengers and respect them, and lend to Allah a good debt. I will cover your sins and give you gardens in which rivers flow. So whoever of you disbelieves after that has gone astray from the right path."
