Why? G-d chose the Jewish People

G-d chose the Jewish people "...because he loved thy fathers, therefore he chose their seed after them, and brought thee out in his sight with his mighty power out of Egypt."  Deuteronomy 4:37.

"The L-RD did not set his love upon you, nor choose you, because ye were more in number than any people, for ye were the fewest of all people: But because the L-RD loved you, and because he would keep the oath which he had sworn unto your fathers, hath the L-RD brought you out with a mighty hand, and redeemed you out of the house of bondmen, from the hand of Pharaoh king of Egypt.  Know therefore that the L-RD thy G-d, he is G-d, the faithful G-d, which keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations;"    There is also a WARNING "And repayeth them that hate him to their face, to destroy them: he will not be slack to him that hateth him, he will repay him to his face."  Deuteronomy 7:7-

Oh, that we might be a blessing to our children like Abraham, Isaac, and Jacob were to their children.  Because of their faithfulness and believing G-d's word they were able to bless their children to many generations.
