Matthew 20:1

For (gar). The parable of the house illustrates the aphorism in Luke 19:30 . A man that is a householder (anqrwpwi oikodespoth). Just like anqrwpwi basilei ( Luke 18:23 ). Not necessary to translate anqrwpwi, just "a householder."

Early in the morning (ama prwi). A classic idiom. Hama as an "improper" preposition is common in the papyri. Prwi is just an adverb in the locative. At the same time with early dawn, break of day, country fashion for starting to work. To hire (misqwsasqai). The middle voice aorist tense, to hire for oneself.
