Toward Asuppim two and two - It is conjectured that the "store-house" in question (1-Chronicles 26:15 note) had two doors, to each of which two porters were appointed.
Eastward were six Levites - It is supposed that there were more guards set at this eastern gate, because it was more frequented than the others. At each of the other gates were only four; at this, six.
Eastward [were] six Levites, northward four a day, southward four a day, and toward Asuppim (i) two [and] two.
(i) Meaning two one day and two another.
Eastward were six Levites,.... The eastern gate, being the way of entrance into the temple, required more porters:
northward four a day; in the daytime, or every day, where was the gate Teri or Tedi, 1-Chronicles 26:14, southward four a day: at the two gates of Huldah, 1-Chronicles 26:15 and toward Asuppim two and two; which were two gates, two at each gate, 1-Chronicles 26:15.
Eastward were six Levites--because the gate there was the most frequented. There were four at the north gate; four at the south, at the storehouse which was adjoining the south, and which had two entrance gates, one leading in a southwesterly direction to the city, and the other direct west, two porters each. At the Parbar towards the west, there were six men posted--four at the causeway or ascent (1-Chronicles 26:16), and two at Parbar, amounting to twenty-four in all, who were kept daily on guard.
Six - For that being the chief gate of the temple required a better guard.
