'Thirty' in the Bible

Solomon's provision for one day was thirty measures of fine flour, and sixty measures of meal,

King Solomon raised a levy out of all Israel; and the levy was thirty thousand men.

The house which king Solomon built for Yahweh, its length was sixty cubits, and its breadth twenty [cubits], and its height thirty cubits.

For he built the house of the forest of Lebanon; its length was one hundred cubits, and its breadth fifty cubits, and its height thirty cubits, on four rows of cedar pillars, with cedar beams on the pillars.

He made the porch of pillars; its length was fifty cubits, and its breadth thirty cubits; and a porch before them; and pillars and a threshold before them.

He made the molten sea of ten cubits from brim to brim, round in compass, and its height was five cubits; and a line of thirty cubits encircled it.
