Mithali 25 : 13 Proverbs chapter 25 verse 13

Kama baridi ya theluji wakati wa mavuno; Ndivyo alivyo mjumbe mwaminifu kwao wamtumao; Kwa maana huwaburudisha bwana zake nafsi zao.
soma Mlango wa 25

As the cold of snow in the time of harvest, So is a faithful messenger to those who send him; For he refreshes the soul of his masters.
