1 Samuel 20:17-19

Young's Literal Translation

¹⁷ and Jonathan addeth to cause David to swear, because he loveth him, for with the love of his own soul he hath loved him.

¹⁸ And Jonathan saith to him, `To-morrow [is] new moon, and thou hast been looked after, for thy seat is looked after;

¹⁹ and on the third day thou dost certainly come down, and hast come in unto the place where thou wast hidden in the day of the work, and hast remained near the stone Ezel.
