19Now therefore send, hasten in thy cattle and all that thou hast in the field; [for] every man and beast that shall be found in the field, and shall not be brought home, the hail shall come down upon them, and they shall die. 20He that feared the word of Jehovah among the servants of Pharaoh made his servants and his cattle flee into the houses. 21And he that regarded not the word of Jehovah left his servants and his cattle in the field.
