Amosi 4 : 5 Amos chapter 4 verse 5

mkachome sadaka ya shukrani, ya kitu kilichotiwa chachu; mkatangaze sadaka mtoazo kwa hiari na kuzihubiri habari zake; kwa maana ndivyo viwapendezavyo ninyi, enyi wana wa Israeli, asema Bwana MUNGU.

Offer a sacrifice of thanksgiving of that which is leavened, And proclaim free will offerings and brag about them: For this pleases you, you children of Israel," says the Lord Yahweh.
