1 Cor. 14 is a list of commands concerning the use of the gift of tongues; v. 21 quotes Is. 28:11 concerning how this gift would be used to witness against the Jews: "In the law it is written, With men of other tongues and other lips will I speak unto this people...". Is. 28:11 primarily refers to Israel's invaders speaking to the Jews in languages ("tongues") they would not have known.
1 Kor. 14 ni orodha ya maagizo yahusuyo kutumia kipawa cha Ulimi; mstari. 21 unanukuu Isaya 28:11 kuhusu ni jinsi gani kipawa hiki kitatumika kwa kushuhudia juu ya Wayahudi:'Katika sheria imeandikwa, kwa midomo (Ulimi) ya watu wageni na kwa lugha nyingine atasema na watu hawa’ Kwa awali Isaya 28:11 inataja wavamizi wa Israeli wakisema na wayahudi kwa lugha ("Ndimi") ambazo hawakuzifahamu.
