'Burdens' in the Bible
So the Egyptians placed supervisors over them, oppressing them with heavy burdens. The Israelis built the supply cities of Pithom and Rameses for Pharaoh.
Years later, after Moses had grown up, he went out to his own people, and took notice of their heavy burdens. He saw an Egyptian beating up a Hebrew, one of his own people.
Therefore, tell the Israelis, "I am the LORD. I'll bring you out from under the burdens of the Egyptians, and I'll deliver you from their bondage. I'll redeem you with an outstretched arm and with great acts of judgment.
I'll take you for my own people, and I'll be your God. Then you will know that I am the LORD your God, who brings you out from under the burdens of the Egyptians.
