'Vigorous' in the Bible

The midwives said to Pharaoh, “The Hebrew women are not like the Egyptian women, for they are vigorous and give birth before a midwife can get to them.”

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].
