to rejoice, to exult: to break out in loud, festive joy, the kind that shows itself rather than staying quiet inside.
This is joy at full volume. English Bibles usually smooth it to "rejoice," but it points to gladness that spills over into shouting and celebration. It is one of the strongest joy words in the Hebrew Bible, and the writers save it for the biggest moments: rescue, the arrival of a king, the day God acts, the new world he promises. Tellingly, it never once appears in the books of the Law or in the long histories from Joshua through Kings. It belongs to worship, to the Psalms, and above all to the prophets. It is a word for the festival, not for quiet contentment at home.
Almost every time, the joy has a reason or an object attached, and that object is almost always God: people rejoice in the LORD, in his saving help, in his faithful love. Wider still, the whole created order can be summoned to rejoice when God takes up his reign, and in two striking lines God himself is the one rejoicing, celebrating over his rescued people like a bridegroom. Once in a while the word simply names glad human delight, a father's pride in a good son or the joy of lovers.
Because the word is so tied to right and worthy joy, it jars when the Bible aims it at the wrong target. People who take delight in doing evil, or who gloat over an enemy brought low, are borrowing the language of the festival for something it was never meant to celebrate. These are all shades of one action, not separate words: the verb names the outburst of joy itself, and that outburst can be pointed at almost anything.
Nuances
Whether the verb in Hosea 10:5 is the ordinary "to rejoice" (describing the priests' now-ended joy over the calf idol's glory) or a separate, otherwise unattested homonym meaning "to tremble," proposed to fit the verse's surrounding mourning.
- majorityThe verb is the ordinary "rejoice," read as the priests' joy over the idol that is over now that its glory has departed; no separate root need be posited, and no current lexicon accepts one.; HALOT (Koehler-Baumgartner-Stamm), s.v. גיל, 1:189-190; DCH (Clines, ed.), vol. 2, s.v. גיל
- minorityA separate homonym "to tremble," compared to an Arabic root, should be recognized here so the priests tremble alongside the people's mourning rather than rejoice.; BDB (Brown-Driver-Briggs), s.v. גיל, p. 162
