Matthew 23:23-24
Woe unto you, scribes and Pharisees, hypocrites! For ye pay tithe of mint and anise and cummin, and have omitted the weightier matters of the law, judgment, mercy, and faith: These ought ye to have done, and not to leave the other undone. Ye blind guides, which strain at a gnat, and swallow a camel.
Luke 11:42
But woe unto you, Pharisees! For ye tithe mint and rue and all manner of herbs, and pass over judgment and the love of God: These ought ye to have done, and not to leave the other undone.
Luke 18:9-14
And he spake this parable unto certain which trusted in themselves that they were righteous, and despised others: Two men went up into the temple to pray; the one a Pharisee, and the other a publican. The Pharisee stood and prayed thus with himself, God, I thank thee, that I am not as other men are, extortioners, unjust, adulterers, or even as this publican. I fast twice in the week, I give tithes of all that I possess. And the publican, standing afar off, would not lift up so much as his eyes unto heaven, but smote upon his breast, saying, God be merciful to me a sinner. I tell you, this man went down to his house justified rather than the other: For every one that exalteth himself shall be abased; and he that humbleth himself shall be exalted.
Which is the first commandment of all? And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord: And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: This is the first commandment. And the second is like, namely this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these.
Luke 20:45-47
And he said unto them in his doctrine, Beware of the scribes, which love to go in long clothing, and love salutations in the marketplaces, And the chief seats in the synagogues, and the uppermost rooms at feasts: Which devour widows' houses, and for a pretence make long prayers: These shall receive greater damnation.
Luke 21:1-4 And Jesus sat over against the treasury, and beheld how the people cast money into the treasury: And many that were rich cast in much. And there came a certain poor widow, and she threw in two mites, which make a farthing. And he called unto him his disciples, and saith unto them, Verily I say unto you, That this poor widow hath cast more in, than all they which have cast into the treasury: For all they did cast in of their abundance; but she of her want did cast in all that she had, even all her living.
Jesus never commands anyone to tithe. God had already established the tithe command through Moses and the Mosaic Law (Law of Moses), for ancient Israel. According the Bible, tithing was part of Jewish law that was practiced among ancient Jewish people – not Gentiles. That said orthodox Jews still give 10% of their income to charity, where as Christians give a free-will offering to their church.
