Genesis 26:5

2 And Jehovah appeareth unto him, and saith, `Go not down towards Egypt, tabernacle in the land concerning which I speak unto thee,

3 sojourn in this land, and I am with thee, and bless thee, for to thee and to thy seed I give all these lands, and I have established the oath which I have sworn to Abraham thy father;

4 and I have multiplied thy seed as stars of the heavens, and I have given to thy seed all these lands; and blessed themselves in thy seed have all nations of the earth;

5 because that Abraham hath hearkened to My voice, and keepeth My charge, My commands, My statutes, and My laws.`

6 And Isaac dwelleth in Gerar;

7 and men of the place ask him of his wife, and he saith, `She [is] my sister:` for he hath been afraid to say, `My wife -- lest the men of the place kill me for Rebekah, for she [is] of good appearance.`

8 And it cometh to pass, when the days have been prolonged to him there, that Abimelech king of the Philistines looketh through the window, and seeth, and lo, Isaac is playing with Rebekah his wife.
