1Ki 9:22-23
Solomon did not make Israelites into tributary slaves; but they were warriors, ministers, and civil and military officers. עבדים are the king’s servants; שׂרים, the heads of the military and civil service; שׁלשׁים, royal adjutants (see at 2Sa 23:8); וּפרשׁיו רכבּו שׂרי, captains over the royal war-chariots and cavalry. - For 1Ki 9:23 compare 1Ki 5:16.
