Apart from the clear parallel between "tongues" and "languages" in Acts 2:4-11, "tongues" is very evidently used to mean "languages" in other parts of the New Testament; the phrase "peoples, and nations, and tongues" is used five times in Revelation to speak of all the peoples of planet earth (Rev. 7:9; 10:11; 11:9; 13:7; 17:15). The Greek word for "tongues" occurs in the Greek version of the Old Testament (called the 'Septuagint') in the sense of languages (see Gen. 10:5; Deut. 28:49; Dan. 1:4).
Katika matendo ya mitume 2: 4-11 lugha zilizoandikwa zipo bayana na sehemu nyingine ya maandiko ya Agano Jipya; maneno "Watu wa kila Taifa na Lugha" yametumika mara tano katika Ufunuo kwa kusema watu wote walio kwenye sayari -dunia hii (Uf. 7: 9, 10:11, 11:9, 13:7, 17:15).Neno la Kiyunani‘ Ulimi’linatokea katika toleo la Kiyunani la Agano la Kale (Liitwalo'Septuagint’) na maana ya lugha (tazama mwa. 10:5, Kum. 28:49, Dan. 1:4) - katika Biblia yetu ya Kiswahili Kum. 28:49 ni sawa na Kiyunani.
