Quoting Commentary for II Chronicles 8:18

וַיִּֽשְׁלַֽח־לוֹ֩ חוּרָ֨ם בְּיַד־עֲבָדָ֜יו אוניות [אֳנִיּ֗וֹת] וַעֲבָדִים֮ י֣וֹדְעֵי יָם֒ וַיָּבֹ֜אוּ עִם־עַבְדֵ֤י שְׁלֹמֹה֙ אוֹפִ֔ירָה וַיִּקְח֣וּ מִשָּׁ֔ם אַרְבַּע־מֵא֥וֹת וַחֲמִשִּׁ֖ים כִּכַּ֣ר זָהָ֑ב וַיָּבִ֖יאוּ אֶל־הַמֶּ֥לֶךְ שְׁלֹמֹֽה׃ (פ)

And Huram sent him by the hands of his servants ships, and servants that had knowledge of the sea; and they came with the servants of Solomon to Ophir, and fetched from thence four hundred and fifty talents of gold, and brought them to king Solomon.

Rashi

Six hundred sixty-six. Chirom gave him 120 [talents], the Queen of Sheva 120, the ships of Tarshish brought from Ophir 420, totaling 660 [talents]. I do not know from where the other six came. It is written in Divrei Hayomim that [the ships brought] from Ophir 450 [talents],4See II Divrei Hayomim 8:18. however it does not include the 120 talents of Chirom. We can resolve the contradictions that the extra 30 were from the 120 of Chirom, because Chirom’s servants were in Ophir with his servants.
