For the Lord's portion is his people;

The song that Moses taught the children of Israel is chapter 32 and tucked away in verse 9 is this:

9. For the Lord's portion is his people;

It was no easy path for God to raise up a people so God's son could be raised under God's law. A lot of people, both Abraham's decendants as well as the nations surrouning them, lost their lives in the quest to disguard God's covenant and his people which were both nessessary to bring Jesus to us.

John 3:14 And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:
15. That whosoever believeth in him should not perish, but have eternal life.
16. For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
17. For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
18. He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
