flame: fire seen as a leaping, blazing tongue of light and heat
This word names flame: the bright, leaping fire that blazes off something burning. It is rare, standing clearly only at Genesis 3:24, where God posts the winged guardians and "the flame of the whirling sword" to block the way back to the tree of life. The related verb meaning "to blaze" or "to burn up" (לָהַט) is far more common, and it almost always describes fire that consumes, from the burning judgment of Deuteronomy 32 to the furnace-like day of Malachi 3.
Hebrew keeps a small cluster of words for fire and its flame, and they shade into one another: the plain word for "fire" (אֵשׁ), the common word for "flame" (לֶהָבָה), a "torch" (לַפִּיד), and a near-twin of this word (לָהַב) that means both "flame" and the "blade" of a weapon. That last overlap matters at Eden: because a flame and a blade can be named by the same kind of word, the guarding "flame of the sword" has been read both as literal fire and as the flashing edge of the blade itself.
Wherever this flame appears, its feel is danger and holiness together: it both dazzles and consumes. At the garden it is not a punishment falling on anyone but a barrier, a burning guard set across the road home.
