See mkgal1's post 448.
Psalm 97
5 The hills melted like wax at the presence of the Lord, at the presence of the Lord of the whole earth.
Did the hills melt? If so, which ones and when?
Psalm 18
7 Then the earth shook and trembled; the foundations also of the hills moved and were shaken, because he was wroth.
8 There went up a smoke out of his nostrils, and fire out of his mouth devoured: coals were kindled by it.
9 He bowed the heavens also, and came down: and darkness was under his feet.
10 And he rode upon a cherub, and did fly: yea, he did fly upon the wings of the wind.
11 He made darkness his secret place; his pavilion round about him were dark waters and thick clouds of the skies.
12 At the brightness that was before him his thick clouds passed, hail stones and coals of fire.
When?
Back to genetics.
We're all Jews.
We're all "blood descendants".
We're all genetically chosen.
But only true believers are spiritually chosen.
They are the true and only Chosen People.
