A.T. Robertson Commentary Matthew 13:24

"Another parable set he before them, saying, The kingdom of heaven is likened unto a man that sowed good seed in his field:" — Matthew 13:24 (ASV)

Set he before them (παρεθηκεν). So again in 13:31. He placed another parable beside (παρα) the one already given and explained. The same verb (παραθεινα) occurs in Lu 9:16.

Is likened (ωμοιωθη). Timeless aorist passive and a common way of introducing these parables of the kingdom where a comparison is drawn (18:23; 22:2; 25:1). The case of ανθρωπω is associative instrumental.
