Tithing supports those who devote themselves serving GODs children
Numbers 18: 25–26
“The LORD said to Moses: SPEAK TO THE LEVITES SAY TO THEM. WHEN YOU RECEIVE FROM THE ISRAELITES THE TITHE I GAVE YOU AS YOUR INHERITANCE, YOU TOO MUST PRESENT A TENTH OF THAT TITHE BACK TO THE LORD.”
Even the Levities who were ministers, had to tithe to support the LORDS WORK. No one is exempt from returning to GOD a portion of what they have received. Though the Levities owned no land nor operated any businesses they were to treat the tithe they received as everyone else did by giving a portion to care for the needs of those who serve GODs children. The Tithing principle is still relevant today, GOD does not need our tithe but it shows obedience to HIS WORD & HIS WILL. GOD expects us all to supply the material needs of those who devote themselves to meeting the Spiritual needs of HIS community of the Faithful.
