Hesabu 18:26

“Sema na Walawi na uwaambie: ‘Mtakapopokea zaka kutoka kwa Waisraeli ambayo ninawapa kama urithi wenu kutoka kwao, ni lazima mtoe sehemu ya kumi ya hiyo zaka kama sadaka kwa Bwana, iwe zaka ya hiyo zaka.

Thus speak unto the Levites, and say unto them, When ye take of the children of Israel the tithes which I have given you from them for your inheritance, then ye shall offer up an heave offering of it for the LORD, even a tenth part of the tithe.
