והקימותי את בריתי אתכם, “I will maintain My covenant with you.” This is the covenant I established with your forefathers that I will multiply you to become as numerous as the stars in heaven and the dust on the earth. (Genesis 26,4 and Genesis 28,14, Ibn Ezra)
Ibn Ezra
has increased you in Egypt, thus fulfilling the blessing given to their ancestor [Genesis 26: 4] [see also Genesis 28: 14].
