These two things will overtake you in a moment, in a single day: loss of children, and widowhood. They will come upon you in full measure, in spite of your many sorceries and the potency of your spells.
KJV
But these two [things] shall come to thee in a moment in one day, the loss of children, and widowhood: they shall come upon thee in their perfection for the multitude of thy sorceries, [and] for the great abundance of thine enchantments.
ASV
but these two things shall come to thee in a moment in one day, the loss of children, and widowhood; in their full measure shall they come upon thee, in the multitude of thy sorceries, and the great abundance of thine enchantments.
