'Burdens' in the Bible

So they set taskmasters over them to oppress them with hard labor. And the sons of Israel built Pithom and Raamses as storage cities for Pharaoh.

One day, after Moses had grown [into adulthood], it happened that he went to his countrymen and looked [with compassion] at their hard labors; and he saw an Egyptian beating a Hebrew, one of his countrymen.

But the king of Egypt said to Moses and Aaron, “Why do you take the people away from their work? Get back to your burdens!”

Pharaoh said, “Look, the people of the land are now many, and you would have them stop their work!”

Therefore, say to the children of Israel, ‘I am the Lord, and I will bring you out from under the burdens of the Egyptians, and I will free you from their bondage. I will redeem and rescue you with an outstretched (vigorous, powerful) arm and with great acts of judgment [against Egypt].

Then I will take you for My people, and I will be your God; and you shall know that I am the Lord your God, who redeemed you and brought you out from under the burdens of the Egyptians.
