The Lord GOD hath given me the tongue of the learned, that I should know how to speak a word in season to him that is weary: he wakeneth morning by morning, he wakeneth mine ear to hear as the learned.
The Lord God hath given me the tongue of the learned, that I should know how to speak a word in season to (him that is) weary. Messiah, as 'the servant of Yahweh' (Isaiah 42:1), declares that the office has been assigned to Him of encouraging the "weary" exiles of Israel, by 'words in season' suited to their case; and that, whatever sufferings it is to cost Himself, He does not shrink from it (Isaiah 50:5-6), because He knows that His cause will triumph at last (Isaiah 50:7-8).
Learned - not in mere human learning, but in divinely taught modes of instruction and eloquence (Isaiah 49:2). So Moses the type (Exodus 4:11-12; Matthew 7:28-29; Matthew 13:54).
Speak a word in season - (Proverbs 15:23; Proverbs 25:11). [La`uwt, akin to `eet (H6256), time, or fit time.] Buxtorf makes the literal sense to be as the English version. So the Septuagint, and Arabic. But Maurer, after the Vulgate [sustentare], makes it from an Arabic root, 'to succour by word'-namely, in their season of need-the "weary" dispersed children of Israel (Deuteronomy 28:65-67). Also the spiritually "weary" (Isaiah 42:3; Matthew 11:28).
He wakeneth (me) morning by morning. Compare "daily rising up early," Jeremiah 7:25; Mark 1:35. The image is drawn from a master wakening his pupils early for instruction.
He wakeneth mine ear - He prepares me for receiving His divine instructions.
To hear as the learned - as one taught by Him, He 'learned obedience,' experimentally, "by the things which He suffered," thus gaining that practical learning which adapted Him for 'speaking a word in season' to suffering men (Hebrews 5:8).
