Yakobo 5:12

Zaidi ya yote, ndugu zangu, msiape, iwe kwa mbingu au kwa dunia, au kwa kitu kingine chochote. “Ndiyo” yenu na iwe ndiyo, na “Hapana” yenu iwe hapana, la sivyo mtahukumiwa.

But above all things, my brethren, swear not, neither by heaven, neither by the earth, neither by any other oath: but let your yea be yea; and your nay, nay; lest ye fall into condemnation.
