כְּסִילkesil meaning in Biblical Hebrew
fool (the stubborn one who repeats his folly); Orion · noun, masculine
Also spelled in English: keciyl

The kesil already got burned once, yet walks right back into the fire—and ancient Israel saw him bound in the winter stars.
כְּכֶלֶב שָׁב עַל־קֵאוֹ כְּסִיל שׁוֹנֶה בְאִוַּלְתּוֹ
“As a dog returns to its vomit, so a fool repeats his folly. (Proverbs 26:11)”
Think of a bad habit or blunder you return to even though you know how it ends: that self-defeating loop is the kesil.
