Nehemiah 2:10

The name Sanballat is probably Babylonian the first element being the same which commences “Sennacherib,” namely, “Sin,” the moon-God, and the second balatu, “eminent” (?),which is found in the Assyrian name, Bel-balatu. As a Horonite, he was probably a native of one of the Bethhorons, the upper or the lower (see Joshua 16:3, Joshua 16:5; 2 Chronicles 8:5), and therefore born within the limits of the old kingdom of Samaria. Tobiah seems to have been an Ammonite slave, high in the favor of Sanballat, whom he probably served as secretary Nehemiah 6:17 and chief adviser.

It grieved them - Compare Ezra 4:4; Ezra 5:6. The revival of Jerusalem as a great and strong city, which was Nehemiah’s aim, was likely to interfere with the prosperity, or at any rate the eminence, of Samaria.
