Exodus 8:27

“And they will listen to your voice; and you with the elders of Israel will come to the king of Egypt, and you all will say to him, ‘Yahweh, the God of the Hebrews, has met with us. So now, please, let us go a three days’ journey into the wilderness, that we may sacrifice to Yahweh our God.’

“Then You performed signs and wonders against Pharaoh, Against all his servants and all the people of his land; For You knew that they acted presumptuously toward them, And made a name for Yourself as it is this day.
