• Hiligaynon: “But I (was) not able to come here immediately, because for a period/[lit. inside] of 21 days the leader/[lit. head] of the kingdom of Persia hindered me. (It was) good that Micael one of the leaders/[lit. heads] of the angels helped me, because I (was) the only one fighting against the leader/[lit. head] of Persia.” (Source: Hiligaynon Back Translation)
