Are all Nations blessed?Abraham's grandson Jacob and his 12 sons: With Tazapa.

Psalms 105:8-10 [8]He hath remembered his covenant for ever, the word which he commanded to a thousand generations. [9]Which covenant he made with Abraham, and his oath unto Isaac; [10]And confirmed the same unto Jacob for a law, and to Israel for an everlasting covenant: Jeremiah 31:9 [9]They shall come with weeping, and with supplications will I lead them: I will cause them to walk by the rivers of waters in a straight way, wherein they shall not stumble: for I am a father to Israel, and Ephraim is my firstborn. Joel 2:27 [27]And ye shall know that I am in the midst of Israel, and that I am the LORD your God, and none else: and my people shall never be ashamed.
