to luxuriate in something: to take rich, unhurried pleasure in it, the way a person of leisure enjoys comfort
The pleasure this word names is not ordinary gladness. It belongs to the language of soft living: rich food, warm care, a life cushioned from hardship. When the Hebrew Bible wants a word for the enjoyment of someone who has never had to go without, this is the word it reaches for.
That is what makes it startling wherever God is the one enjoyed. "Delight yourself in the LORD" (Psalm 37:4) is not asking for polite religious satisfaction. It borrows the vocabulary of luxury and points it at God, as though he were the rich table a person settles down to. Isaiah does this on purpose. The same word he strips from Babylon he hands back to Zion in chapters 55, 58, and 66, and at Isaiah 58:13 its noun (עֹנֶג) becomes the name given to the Sabbath itself.
That same verse tells this pleasure apart from a plainer one (חָפֵץ), the ordinary word for what a person wants or is set on. Doing your own pleasure on the Sabbath is the thing forbidden; calling the Sabbath a delight is the thing commanded. Two kinds of enjoyment, separated in a single sentence.
The senses gathered here are one motion seen from three angles:
- delighting in God himself, the settled hope of the psalms and the wisdom books
- luxuriating in something rich and plentiful, whether good food, tender care, or a long peace
- turning that same enjoyment against another person, which is how Isaiah 57:4 appears to use it
Nuances
Whether the Hithpael in Isaiah 57:4 is a distinct pejorative sub-sense (make merry over, make sport of) or the ordinary sense take exquisite delight in, deployed ironically with a human object.
