Leviticus 19-20

Be holy because I, the Lord your God, am holy. Each of you must respect your mother and father, and you must observe my Sabbaths. I am the Lord your God.

When you sacrifice a fellowship offering to the Lord, sacrifice it in such a way that it will be accepted on your behalf. It shall be eaten on the day you sacrifice it or on the next day.

When you reap the harvest of your land, do not reap to the very edges of your field or gather the gleanings of your harvest.  Leave them for the poor and the foreigner. I am the Lord your God.

Do not eat any meat with the blood still in it.

Stand up in the presence of the aged, show respect for the elderly and revere your God. I am the Lord. 

Say to the Israelites: ‘Any Israelite or any foreigner residing in Israel who sacrifices any of his children to Molek is to be put to death. The members of the community are to stone him. 

If a man commits adultery with another man’s wife—with the wife of his neighbor—both the adulterer and the adulteress are to be put to death.

Why?

Because the Lord is Holy, every Israelite and every Christian needs to keep a holy life, no immoral sexual relationships with others.

How?

This generation is a evil generation, many sins and idol worship are popular, may the Lord blesses me living with pure hear, clean mind and honor the Holy name of the Lord.
