Jesus gave us a parable about that. He said the pharisees all gave their tithes, a little old woman threw 2 small coins in. Jesus said hers had more value than all the tithes combined. She gave from the heart. That is the new covenant=love from the heart, Jesus wants not a tithe by written law. So we are not obligated to tithe. Any teacher asking for the tithe does not know Jesus-RUN FROM THEM. They are these-2Cor 11:12-15
