a blossom: the open flower of a plant, whether growing, carved as ornament, or held up as the picture of what withers fast
Hebrew has more than one word for a plant in bloom, and this one settles on the bloom itself: the open, showy part a plant pushes out. Its nearest neighbor (פֶּרַח) leans toward the bud and the act of sprouting, while this word names the finished flower. Numbers keeps the two side by side when Aaron's staff sprouts, puts out blossoms, and bears ripe almonds overnight.
Because a bloom is the loveliest and the most short-lived thing a field produces, the Bible reaches for it constantly as a picture of a human life. Grass and flower stand together in Isaiah, Job, and the Psalms: the grass dries, the flower drops, and a person's days go the same way. The comparison is never a compliment about beauty. It is a statement about how little time there is.
The temple builders took the word in a third direction, using it for open flowers carved into cedar walls and doors beside gourds and palm trees. That is the same shape rendered in wood: a bloom fixed in place where a real one would already have fallen.
