God is awesome and thanks be to our Lord Jesus, The Christ, we now experience so much more grace now than was dealt in the old testament. Nevertheless, we see that God is very concerned about justice in our homes and communities as the rest of Deuteronomy 19 shows. Please read rest of Deuteronomy 19:5-21
I do want to highlight that God is ready to hand over to us, and has already prepared, wealth, lands, authority for us to use to show mercy to others in trouble, but first we have to prove and show our obedience before He does. The same blessings promised to our spiritual ancestors (Patriarchs) apply to us.
Deuteronomy 19:8-9
8 “And if the LORD your God enlarges your territory, as he swore to your ancestors, and gives you all the land he promised them,
9 you must designate three additional cities of refuge. (He will give you this land if you are careful to obey all the commands I have given you—if you always love the LORD your God and walk in his ways.)
Luke 16:10
10 “If you are faithful in little things, you will be faithful in large ones. But if you are dishonest in little things, you won’t be honest with greater responsibilities.
