In those days after Moses was grown up, he went out to his brethren: and saw their affliction, and an Egyptian striking one of the Hebrews his brethren.
Is not this rather the fast that I have chosen? Loose the bands of wickedness, undo the bundles that oppress. Let them that are broken go free: and break asunder every burden.
And the Lord said to him: I have seen the affliction of my people in Egypt, and I have heard their cry; because of the rigour of them that are over the works.
And they that were over the works of the children of Israel were scourged by Pharao's taskmasters, saying: Why have you not made up the task of bricks both yesterday and today as before?
Therefore say to the children of Israel: I am the Lord who will bring you out from the work prison of the Egyptians; and will deliver you from bondage, and redeem you with a high arm, and great judgments.
And I will take you to myself for my people. I will be your God: and you shall know that I am the Lord your God, who brought you out from the work prison of the Egyptians.
