This name appears only in Luke's account of the wealthy chief tax collector who climbed a sycamore tree to see Jesus passing through Jericho (Luke 19). The Hebrew root (זַכַּי) carries connotations of purity or righteousness—an ironic contrast to the social stigma attached to tax collectors in first-century Judea. Luke's narrative turns on this tension: the man whose name means "righteous" is precisely the one religious leaders would have considered unrighteous. When Jesus calls him down and declares salvation has come to his house, the story fulfills the meaning embedded in his name. The multilingual forms (French Zachée, Spanish Zakchaîos) preserve the Greek transliteration of the Hebrew original.
