John Gill, on Neh 2:9

“And I came to the governors of the country beyond the river, and gave them the king’s letters. And the king had sent with me captains of soldiers, and horsemen.”

“Then I came to the governors beyond the river,.... Who these governors were, whether the same who were in the second year of this king's reign eighteen years ago, Tatnai and Shetharboznai, is not certain: now the king had sent captains of the army and horsemen with me; both to do him honour, and for his safety; and coming thus attended, must serve to recommend him to the governor, who received him from them at the river Euphrates, and conducted him to Judah.”
