16 By my own self have I sworn, saith the Lord: because thou hast done this thing, and hast not spared thy only begotten son for my sake:17 I will bless thee, and I will multiply thy seed as the stars of heaven, and as the sand that is by the seashore: thy seed shall possess the gates of their enemies.18 And in thy seed shall all the nations of the earth be blessed, because thou hast obeyed my voice.
