'Solid' in the Bible

You shall make two cherubim (winged angelic figures) of [solid] hammered gold at the two ends of the mercy seat.

“His heart is as hard as a stone,Indeed, as solid as a lower millstone.

Like a [common] clay vessel covered with the silver dross [making it appear silver when it has no real value]Are burning lips [murmuring manipulative words] and a wicked heart.

(The Bridegroom)“O my dove, [here] in the clefts in the rock,In the sheltered and secret place of the steep pathway,Let me see your face,Let me hear your voice;For your voice is sweet,And your face is lovely.”
