“pledge”
in Edition Clear Qur'an by Talal Itani / Yusuf (Joseph)
12:66He said, “I will not send him with you, unless you give me a pledge before God that you will bring him back to me, unless you get trapped.” And when they gave him their pledge, he said, “God is witness to what we say.”
12:80And when they despaired of him, they conferred privately. Their eldest said, “Don’t you know that your father received a pledge from you before God, and in the past you failed with regard to Joseph? I will not leave this land until my father permits me, or God decides for me; for He is the Best of Deciders.”

Those who spend their wealth by night and day, privately and publicly, will receive their reward from their Lord. They have nothing to fear, nor shall they grieve.
