The greater number of expositors explain a disciple's tongue by: "A tongue such as instructed people or scholars possess,--an eloquent tongue." But למד, everywhere else in Isaiah, means "pupil," "disciple," and is used especially of the disciples of the Lord, those who go to His school, are instructed by Him; comp. chaps. viii. 16; liv. 13. A disciple's tongue is such as the disciples of the Lord possess. Its foundation is formed by the disciple's _ear_ mentioned at the close of the verse. He who hears the Lord's words, speaks also the Lord's words. The signification, "learned," is not suitable in the last clause of the verse, and its reference to the first does not permit of our assuming a different signification in either clause. Just as here the Servant of God traces back to God that which He speaks, so Jesus says, in John viii. 26: κᾀγὼ ἃ ἤκουσα παρʼ αὐτοῦ ταῦτα λαλῶ εἰς τὸν κόσμον, comp. iii. 34: ὃν γὰρ ἀπέστειλεν ὁ θεὸς τὰ ῥήματα τοῦ θεοῦ λαλεῖ. The verb סמך, which occurs only here, means, according to the Arabic, "to help," "to support;" _Aquila_: ὑποστηρίσαι, Vulg. _sustentare_. Like other similar verbs, _e.g._, סמך, in Gen. xxvii. 37, it is construed with a double accusative: "that I may help the weary, word," _i.e._, may support him by comforting words. The weary or fatigued are, like the bent reed, the faintly burning wick, in chap. xlii. 3; the blind, the prisoners sitting in darkness, _ibid._, ver. 7; the broken-hearted, chap. lxi. 1; them that mourn, _ibid._, ver. 2. Just as here the Servant of God represents the suffering and afflicted ones as the main objects of His mission, so Christ announces, that His mission is specially directed to these, comp. _e.g._, Matt. v. 4; xi. 28. In order to be able to fulfil this mission. He must be able to draw from the fulness of God, who looketh to him that is poor and of a contrite spirit, chap. lxvi. 2, and who alone understands to heal the broken in heart, and to bind up their wounds, Ps. cxlvii. 3.--In the words: "He wakeneth, &c." we are told in what manner the Lord gives to His Servant the disciple's tongue. _To waken_ [Pg 252] _the ear_ is equivalent to: to make attentive, to make ready for the reception of the divine communications. The expression "morning by morning" indicates that the divine wakening is going on uninterruptedly, and that the Servant of God unreservedly surrenders himself to the influences which come from above, in which He has become an example to us. Ver. 5. "_The Lord Jehovah hath opened mine ear, and I was not rebellious, and have not turned back._"
