ἀγαλλιαθῆναι [3 verses](verb aor inf pass) "To rejoice" is agalliao means "rejoice exceedingly" and is a later form of agallomai, which means to "glorify," and "exalt," especially the idea of "paying honor" to God. - -- The verb translated as "rejoiced", which literally means "much leaping" and generally, to "celebrate." Jesus uses it only three times. This word doesn't appear in non-biblically influenced Greek. It appears first in the Greek OT where it translated many different Hebrew words that mean "rejoin," "be glad," "shout," "exalt,"  and so on. This word is a version of a more common Greek word that means "glorify," and "exalt," but the Judean use of this word seems broader.
