‏ 1 Kings 9:23

These [were] the chief of the officers that [were] over Solomon's work, {i} five hundred and fifty, which bare rule over the people that wrought in the work.

(i) The overseers of Solomon's works were divided into three parts: the first contained 3300, the second 300, and the third 250 who were Israelites. Here are the two last parts, which make 550. See 2Ch 8:10.
