逃城 literally for Israelites who have/know/obey God's LAWS,
(eye for eye, tooth for tooth, life for life,
there is no exceptions here, no matter what)
God gave them EXTRA GRACE in case bad things happened
by accident (not on purpose) to protect both PARTIES.

I bet Israelites knew that:the only ONE and TRUE God
gave them EXTRA GRACE.

旧约的逃城预表了基督的救赎及教会的功能
is well preached and accepted in church.
but
you guys refuse to acknowledge the FACT
基督的救赎 never imply he promise to restore believers'
body-soul-spirit on earth, except 'I will never leave you and
I will never forsake you'.
