'Solid' in the Bible

the lampstands, and the lamps for burning according to the custom before the inner sanctuary, of solid gold;

and the blossoms, the lamps, and the tongs that [were] of solid gold;

and the snuffers, the drinking bowls, the dishes, and the firepans, of solid gold; and the entrance to the house, the inner doors to {the most holy place}, and the doors to the house of the temple [were] of gold.

And [the] captain of [the] guard [took] the bowls, and the firepans, and the sprinkling bowls, and the pots, and the lampstands, and the pans, and the libation bowls, {those made of solid gold} and {those made of solid silver}.

I gave you milk to drink, not solid food, for you were not yet able [to eat it]. But now you are still not able,

However, the solid foundation of God stands firm, having this seal: "The Lord knows those who are his," and "Everyone who names the name of the Lord must abstain from unrighteousness."

For indeed, [although you] ought to be teachers {by this time}, you have need of someone to teach you again the beginning elements of the oracles of God, and {you have need of} milk, not solid food.

But solid food is for the mature, who because of practice have trained their faculties for the distinguishing of both good and evil.
