They will pursue you and overtake you until you are destroyed

Deuteronomy 28:45-57

All these curses will come on you. They will pursue you and overtake you until you are destroyed, because you did not obey the Lord your God and observe the commands and decrees he gave you. 

The Lord will bring a nation against you from far away, from the ends of the earth, like an eagle swooping down, a nation whose language you will not understand,  a fierce-looking nation without respect for the old or pity for the young. 

Because of the suffering your enemy will inflict on you during the siege, you will eat the fruit of the womb, the flesh of the sons and daughters the Lord your God has given you.

Some of this catalog of horror was later to befall the people, even to the obscenities of siege.

Why?

These curses are horror and terrible because they did not obey the words of the Lord.

How?

Away from the decease and horror is chose walking on the way of the Lord.
