Yeremia 9 : 8 Jeremiah chapter 9 verse 8

Ulimi wao ni mshale ufishao; husema maneno ya hadaa; mtu mmoja husema maneno ya amani na mwenzake kwa kinywa chake, lakini moyoni mwake humwotea.
soma Mlango wa 9

Their tongue is a deadly arrow; it speaks deceit: one speaks peaceably to his neighbor with his mouth, but in his heart he lays wait for him.
