Nehemia 2:15

Then I (went on) ascending the valley and viewing the wall, and so entered by the valley-gate, and returned. ואהי with the participle expresses the continuance of an action, and hence in this place the continuous ascent of the valley and survey of the wall. The נחל which he ascended was doubtless the valley of Kidron (קדרון נחל, Sa2 20:23; Kg1 2:37, and elsewhere). ואבוא ואשׁוּב are connected, שׁוּב expressing merely the idea of repetition (Gesenius, heb. Gram. 142, 3): I came again into the valley-gate. Older expositors incorrectly explain these words to mean, I turned round, traversing again the road by which I had come; Bertheau: I turned to go farther in a westerly direction, and after making the circuit of the entire city, I re-entered by the valley-gate. This sense is correct as to fact, but inadmissible, as requiring too much to complete it. If we take אשׁוּב adverbially, these completions are unnecessary. Nehemiah does not give the particulars of the latter portion of his circuit, but merely tells us that after having ascended the valley of Kidron, he re-entered by the valley-gate, and returned to his residence, obviously assuming, that from the upper part of the vale of Kidron he could only return to the valley-gate at the west by passing along the northern part of the wall.

How Nehemiah wrestled with God and prevailed we read in the foregoing chapter; now here we are told how, like Jacob, he prevailed with men also, and so found that his prayers were heard and answered. I. He prevailed with the king to send him to Jerusalem with a commission to build a wall about it, and grant him what was necessary for it (Neh 2:1-8). II. He prevailed against the enemies that would have obstructed him in his journey (Neh 2:9-11) and laughed him out of his undertaking (Neh 2:19, Neh 2:20). III. He prevailed upon his own people to join with him in this good work, viewing the desolations of the walls (Neh 2:12-16) and then gaining them to lend every one a hand towards the rebuilding of them (Neh 2:17, Neh 2:18). Thus did God own him in the work to which he called him.
