ḥaphets

At its heart this word names a leaning of the whole person toward something the subject finds good. It is not a cool decision but a felt inclination: the thing pleases you, and because it pleases you, you want it. The same word therefore covers both the pleasure ("I delight in this") and the wanting that flows from the pleasure ("I am willing to do this"), and a given verse can sit anywhere along that line.

The two shades below are the same disposition viewed from two angles. When the focus is on a person or thing that pleases the subject, it reads as delighting in or taking pleasure in. When the focus is on an action the subject is drawn to do (or, very often, not drawn to do), it reads as wanting or being willing. Hebrew makes no hard break between them, and many verses could be heard either way.

The word is striking for how often God is its subject. The Bible repeatedly says what God does and does not take pleasure in: not in the death of the wicked, not in mere sacrifice without obedience, but in steady love, in justice, and in his own people. Because the same verb names both God's delight and a human wish, it carries real weight: what pleases God is presented as the measure of what is genuinely good.

This is a separate word that happens to be spelled the same. It appears once, describing the great beast in Job whose tail it "bends" or "stiffens" like a cedar. It has nothing to do with pleasure or desire; the standard reference works treat it as an unrelated root, and it survives only in this single line.

Readers should not let the far more common word for delight color this verse. The picture is purely physical: a massive, rigid tail compared to a tree, not anything the creature wants or enjoys.
