Isai

Isai can represent Isaí, the Spanish biblical form of Jesse, father of King David. This connection is important because Isaí is not simply the same name as Isaías, the Spanish form of Isaiah. Jesse's original Hebrew meaning is uncertain, although “gift” is a traditional suggestion. The unaccented spelling often appears where diacritics are omitted.

Families choosing the Spanish biblical name may want to retain Isaí in contexts that support its accent, since it helps show the intended stress. Isai offers a short written form with a substantial scriptural connection. Compared with Isaiah or Isaac, it may require a little more explanation in English-speaking settings. Its strongest naming story is the Jesse relationship, rather than an assumed translation borrowed from a similar-looking name.
