Beloved, do not offer up to God offerings or tithes whose source is unclean or corrupt. So stealing, deceiving, defrauding, extorting, lying, cheating or prostituting to make a living and then give to the Lord all apply here. Praise Jehovah we are no longer like we we were, i.e. liars and cheats who defraud to make a profit.
Deuteronomy 23:17-18
17 “No Israelite, whether man or woman, may become a temple prostitute.
18 When you are bringing an offering to fulfill a vow, you must not bring to the house of the LORD your God any offering from the earnings of a prostitute, whether a manb or a woman, for both are detestable to the LORD your God.
Malachi 3:5
5 “At that time I will put you on trial. I am eager to witness against all sorcerers and adulterers and liars. I will speak against those who cheat employees of their wages, who oppress widows and orphans, or who deprive the foreigners living among you of justice, for these people do not fear me,” says the LORD of Heaven’s Armies.
Malachi 3:8-12
8“Should people cheat God? Yet you have cheated me! “But you ask, ‘What do you mean? When did we ever cheat you?’
“You have cheated me of the tithes and offerings due to me.
9 You are under a curse, for your whole nation has been cheating me.
10 Bring all the tithes into the storehouse so there will be enough food in my Temple. If you do,” says the LORD of Heaven’s Armies, “I will open the windows of heaven for you. I will pour out a blessing so great you won’t have enough room to take it in! Try it! Put me to the test!
11 Your crops will be abundant, for I will guard them from insects and disease.a Your grapes will not fall from the vine before they are ripe,” says the LORD of Heaven’s Armies.
12 “Then all nations will call you blessed, for your land will be such a delight,” says the LORD of Heaven’s Armies.
