Who is the referent of "his own" in the immediate context, and in the larger context of Jesus statements-Mt. 15:24, 10:5.6, Paul in Rom. 15:8?
How the the identity of the "referent" would affect exegesis of the parable of Sower, and for that matter, other parables,i.e. the "talents" (Mt.25:14-30); "ten virgins()Mt. 25:1-12); the great banquet (Mt. 22:2-9). etc.

Parable of sower Mt. 13: 3-9
And he told them many things in parables, saying: “A sower went out to sow. And as he sowed, some seeds fell along the path, and the birds came and devoured them. Other seeds fell on rocky ground, where they did not have much soil, and immediately they sprang up, since they had no depth of soil, but when the sun rose they were scorched. And since they had no root, they withered away. Other seeds fell among thorns, and the thorns grew up and choked them. Other seeds fell on good soil and produced grain, some a hundredfold, some sixty, some thirty. He who has ears, a let him hear.” (ESV)
