The King James Bible addresses tithing in several passages:
Malachi 3:8-10 (KJV)
8 Will a man rob God? Yet ye have robbed me. But ye say, Wherein have we robbed thee? In tithes and offerings. 9 Ye are cursed with a curse: for ye have robbed me, even this whole nation. 10 Bring ye all the tithes into the storehouse, that there may be meat in mine house, and prove me now herewith, saith the LORD of hosts, if I will not open you the windows of heaven, and pour you out a blessing, that there shall not be room enough to receive it.
Leviticus 27:30 (KJV)
30 And all the tithe of the land, whether of the seed of the land, or of the fruit of the tree, is the LORD’s: it is holy unto the LORD.
Proverbs 3:9-10 (KJV)
9 Honour the LORD with thy substance, and with the firstfruits of all thine increase: 10 So shall thy barns be filled with plenty, and thy presses shall burst out with new wine.
2 Corinthians 9:6-7 (KJV)
6 But this I say, He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully. 7 Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver.
Matthew 23:23 (KJV)
23 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.
