An adjective expressing equality or equivalence, ἴσος appears in contexts where parity — whether fair or provocative — is at stake. The laborers in Jesus' vineyard parable complain that the master has made latecomers 'equal' to those who bore the day's heat (Matt 20:12), exposing human resentment at divine generosity. The false witnesses against Jesus at trial cannot produce 'consistent' testimony (Mark 14:56, 59). Most explosively, Jesus is accused of 'making himself equal with God' (John 5:18), and Phil 2:6 speaks of equality with God as something Christ did not grasp at. Spanish igual and French égal preserve both the mathematical and social dimensions of the word.
