Matthew 13:36

"Then," saith he, "Jesus sent the multitudes away, and went into His house." And not one of the Scribes follows Him; whence it is clear that for no other purpose did they follow, than to take hold of Him. But when they marked not His sayings, thenceforth He let them be. "And His disciples come unto Him, asking Him concerning the parable of the tares;" although at times wishing to learn, and afraid to ask. Whence then arose their confidence in this instance? They had been told, "To you it is given to know the mysteries of the kingdom of Heaven;" and they were emboldened. Wherefore also they ask in private; not as grudging the multitude, but observing their Master's law. For, "To these," saith He, "it is not given." And why may it be that they let pass the parable of the leaven, and of the mustard seed, and inquire concerning this? They let those pass, as being plainer; but about this, as having an affinity to that before spoken, and as setting forth something more than it, they are desirous to learn (since He would not have spoken the same to them a second time); for indeed they saw how severe was the threatening therein uttered. Wherefore neither doth He blame them, but rather completes His previous statements. And, as I am always saying, the parables must not be explained throughout word for word, since many absurdities will follow; this even He Himself is teaching us here in thus interpreting this parable. Thus He saith not at all who the servants are that came to Him, but, implying that He brought them in, for the sake of some order, and to make up the picture, He omits that part, and interprets those that are most urgent and essential, and for the sake of which the parable was spoken; signifying Himself to be Judge and Lord of all.

The Lord sends away the multitude, and enters the house that His disciples might come to Him and ask Him privately of those things which the people neither deserved to hear, nor were able.

Figuratively; Having sent away the multitude of unquiet Jews, He enters the Church of the Gentiles, and there expounds to believers heavenly sacraments, whence it follows, And his disciples came to him, saying, Explain to us the parable of the tares of the field.
