To show the Egyptians that Aaron could do something with his rod that their magicians could not imitate, God caused the serpent into which His rod had been changed to swallow up all the rods of the magicians. But Balaam and his associates said: "There is nothing marvellous or astonishing in this feat. Your serpent has but devoured our serpents, which is in accordance with a law of nature, one living being devours another. If thou wishest us to acknowledge that the spirit of God worketh in thee, then cast thy rod to the earth, and if, being wood, it swallows up our rods of wood, then we shall acknowledge that the spirit of God is in thee." Aaron stood the test. After his rod had resumed its original form, it swallowed up the rods of the Egyptians,[163] and yet its bulk showed no increase. This caused Pharaoh to reflect, whether this wonderful rod of Aaron might not swallow up also him and his throne. Nevertheless he refused to obey the behest of God, to let Israel go, saying, "Had I Jacob-Israel himself here before me, I should put trowel and bucket on his shoulder." And to Moses and Aaron, he said, "Because ye, like all the rest of the tribe of Levi, are not compelled to labor, therefore do ye speak, 'Let us go and sacrifice to the Lord.' If you had asked for a thousand people, or two thousand, I should have fulfilled your request, but never will I consent to let six hundred thousand men go away." THE SUFFERING INCREASES Beside refusing to dismiss the children of Israel, he ordered, on the very day of Moses and Aaron's audience with him, that the people be required to deliver the prescribed tale of bricks, though the taskmasters were not as heretofore to give them straw to make brick. Another decree was, that the children of Israel were not to be permitted to rest on the Sabbath, for Pharaoh knew that they used the leisure for reading the rolls that described their redemption. All this was a part of God's plan, the oppression of Israel was to be increased the closer the end approached. As they wandered up and down the land of Egypt gathering the straw they needed for the due tale of bricks, they were maltreated by the Egyptians if they caught them on their fields. Such unkind acts perpetrated by the whole people made it impossible for them to cast the entire blame for the bondage of Israel upon Pharaoh. All the Egyptians showed cruelty to the Israelites on their straw foraging expeditions, and therefore the Divine punishment descended upon all alike.
