Matendo Ya Mitume 15:1

Baadhi ya watu wakashuka Antiokia kutoka Uyahudi, nao wakawa wanawafundisha wandugu: “Msipotahiriwa kufuatana na desturi aliyofundisha Mose, hamwezi kuokoka.”

And certain men which came down from Judæa taught the brethren, and said, Except ye be circumcised after the manner of Moses, ye cannot be saved.
