Comentario citado sobre II Crónicas 2:1

to gather the strangers who had converted, because he did not wish to make Israelites perform rigorous labor. And so we find with Solomon below (II Chron. 2:1): “And Solomon counted, etc.”; (ibid. verse 17): “And he made of them seventy thousand who bear burdens.” And it is written further (ibid. 8:7): “And all the people remaining from the Hittites, etc., who were not of Israel, etc.”; (ibid. verse 9): “And of the Children of Israel, whom Solomon did not make slaves, etc.”

two hundred fifty And in I Kings (9:23): “five hundred fifty,” but [in fact], these two are identical, for there Scripture deducts three hundred and then repeats and counts them again, for there it is written (5:30): “Besides Solomon’s chief officers, etc....three thousand and three hundred, who bore rule,” and here it is written above (2:1): “three thousand six hundred.” We find that what is missing in one verse is added in the other verse. Scripture separates them because the three hundred extra were proselytes, and they were appointed over those three thousand three hundred who ruled over the seventy thousand who bore burdens and the eighty thousand hewers in the mountains (I Kings 5:29), and these two hundred fifty were Israelites, appointed over those three hundred proselytes.

And he made of them seventy thousand, etc. The reason he mentions them again and mentions the number is that he interrupted the topic; therefore, he had to repeat it again now. And he did not stop until he finished the entire [account of the] building, and he says immediately (3:1): “And Solomon commenced to build, etc.” Now, even with one verse, it is customary to interrupt the topic and [then] to begin [again] with the previous statement, e.g., (Num. 16:6): “Do this: take yourself, etc.” And the morrow, it says (ibid. 16f.): “And Moses said to Korah: You and all your band, etc.,” and he repeats and says, “and let each man take his censer and place, etc.” Since he interrupted with many verses, it was necessary to rewrite it, and how much more so here.
