God did not allow anyone to make an excuse not to give Him His tithe.

Matthew 23:1-3 (NLT)

Then Jesus said to the crowds and to his disciples, 2 “The teachers of religious law and the Pharisees are the official interpreters of the law of Moses. 3 So practice and obey whatever they tell you, but don’t follow their example. For they don’t practice what they teach.

Matthew 23:23 (NLT)

23 “What sorrow awaits you teachers of religious law and you Pharisees. Hypocrites! For you are careful to tithe even the tiniest income from your herb gardens, but you ignore the more important aspects of the law—justice, mercy, and faith. You should tithe, yes, but do not neglect the more important things.

Mark Batterson

"Let me be blunt, because on the subject of money Jesus was. Obedience can be measured in dollars. So can faith. So can sacrifice. It’s certainly not the only measure, but it’s one of the most accurate. If we give God 2 percent of our income, can we really say we are 100 percent committed to Him? I think not. If we withhold the tithe, can we really say, “In God we trust”? If we give God our leftovers instead of the firstfruits, can we really say we’re seeking first His kingdom?" ― from "All In: You Are One Decision Away From a Totally Different Life"
