Vous avez cherché: unprofitable (Anglais - Swahili)

which in time past was to thee unprofitable, but now profitable to thee and to me:
ni onesimo yuleyule ambaye wakati mmoja alikuwa hakufai kitu, lakini sasa ananifaa mimi na wewe pia.

and cast ye the unprofitable servant into outer darkness: there shall be weeping and gnashing of teeth.
na kuhusu huyu mtumishi asiye na faida, mtupeni nje gizani! huko kutakuwa na kilio na kusaga meno.

they are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.
wote wamepotoka wote wamekosa; hakuna atendaye mema, hakuna hata mmoja.

so likewise ye, when ye shall have done all those things which are commanded you, say, we are unprofitable servants: we have done that which was our duty to do.
hali kadhalika na ninyi mkisha fanya yote mliyoamriwa, semeni: sisi ni watumishi tusio na faida, tumetimiza tu yale tuliyotakiwa kufanya."
