"Is it not because"

1. 1 Sam. 10: 1
     1 Then Samuel took a vial of oil, and poured it upon his head, and kissed him, and said, Is it not because the Lord hath anointed thee to be captain over his inheritance?
2. 2 Kgs. 1: 3, 6, 16
     3 But the angel of the Lord said to Elijah the Tishbite, Arise, go up to meet the messengers of the king of Samaria, and say unto them, Is it not because there is not a God in Israel, that ye go to enquire of Baal-zebub the god of Ekron?

     6 And they said unto him, There came a man up to meet us, and said unto us, Go, turn again unto the king that sent you, and say unto him, Thus saith the Lord, Is it not because there is not a God in Israel, that thou sendest to enquire of Baal-zebub the god of Ekron? therefore thou shalt not come down from that bed on which thou art gone up, but shalt surely die.

     16 And he said unto him, Thus saith the Lord, Forasmuch as thou hast sent messengers to enquire of Baal-zebub the god of Ekron, is it not because there is no God in Israel to enquire of his word? therefore thou shalt not come down off that bed on which thou art gone up, but shalt surely die.
