their number of the vessels of the House of the Lord.

basins Heb. אֲגַרְטְלֵי. They are kinds of vessels.

knives Heb. מַחֲלָפִים. They are knives, and this expression refers to the chamber of the knives (בֵּית הַחֲלִיפוֹת). Because they would deposit the knives therein, it was called the chamber of the depository of the knives (לִשְּׁכַּת בֵּית הַחֲלִיפוֹת).
