  17 H3581 And now, I pray thee, let the power H136 of the Lord H1431 be great, H834 according H1696 as thou hast spoken, H559 saying,
  18 H3068 Jehovah H750 is slow to anger, H7227 and abundant H2617 in lovingkindness, H5375 forgiving H5771 iniquity H6588 and transgression; H5352 and that will by no means H5352 clear H6485 the guilty, visiting H5771 the iniquity H1 of the fathers H1121 upon the children, H8029 upon the third H7256 and upon the fourth generation.
