Be generosity to others

Deuteronomy 23:15-25
If a slave has taken refuge with you, do not hand him over to his master. Do not oppress him. Let him free chooses wherever he likes.
No prostitute in Israelite, you must no bring the earning of a prostitute of female or male into the house of the Lord to pay any vow.
Do not charge your brother interest whether on money or food or anything else that may earn interest. You may charge interest to a foreigner.
If you make a vow to the Lord, do not be slow to pay it, for the Lord will certainly demand it of you and you will be guilt of sin. But if you refrain from making a vow, you will not be guilty.
If you enter your neighbor's vineyard, you may eat all the grasps you want, but do not put any in your basket.
Why?
All of these rules are mercy to treat your brothers, help the needed peoples.
The Lord detests the behavior of prostitute and the bring earning of prostitute to His house.
There were female and male prostitutes in Canaan area.  It is existing in this world also.
The Lord does not like the slave system, the Lord hopes every man be free and free in the truth.
Generosity to the poor or needed person, let them eat.
How?
I should be generosity to others for the Lord may bless me in everything I put our hand to in the land I are entering to posses.
