[It] means two [things], both to punish and to consider just; thus Herodotos [uses this verb].[1]
"[He] thinking it just to defend themselves against the Skythians with the same means which they themselves had recourse to, in violation of treaty, against those of the Athenians who were surrendering the citadel."[2]
And elsewhere, Appian [writes]: "...to make agreements on whatever terms the Gabii think just".[3] Meaning consider to be just.
And Josephus: "and they, reckoning the exaction of justice to be an insult, drew down many of the weapons and departed to a certain place."[4]
