As for the matter you and I have spoken about, the Lord will be a witness between you and me forever.”

Jonathan then said to David, “Go in the assurance the two of us pledged in the name of the Lord when we said: The Lord will be a witness between you and me and between my offspring and your offspring forever.” Then David left, and Jonathan went into the city.

So Achish trusted David, thinking, “Since he has made himself detestable to his people Israel, he will be my servant forever.”
