[There is] no speech nor language [where] their voice is not heard,.... Not the voice of the day and night; as if the sense was, that there is no people, of any speech or language under the sun, but there is something said every day and night of the weather, what it is, or will be, as the face of the heavens appears morning and evening: but of the heavens and firmament; the meaning of which some take to be this; either that though they have no proper speech nor language, yet there is a voice in them which is heard, declaring the glory of God and his handiworks; and the words may very well be rendered, "they have no speech nor words, without [these] their voice is heard"; or that there is no people, nation, or language under the heavens; see Da 3:4; though they are ever so different one from another, so as not to be able to understand each other; yet the voice of the heavens, uttering and proclaiming the glory of their Maker, is heard and understood by them all: but rather this is to be interpreted of the extent of the Gospel ministry by the apostles; who, according to their commission, went everywhere preaching the word, to men of all nations, of every speech and language; for which they were qualified, by having the gift of various tongues bestowed upon them; so that there were no nations, of ever so barbarous a speech and language, but they were capable of speaking to and of being understood by them; and though they could not understand one another, they all heard the apostles speak in their own tongues the wonderful works of God, Ac 2:4.
Their voice, in the ministration of the Gospel, was heard in every nation externally, and by many internally: faith came by hearing; and they received the word with gladness and readiness.
