SEV Biblia, Chapter 4:29
y cuando el fruto fuere producido, luego se mete la hoz, porque la siega es llegada.
Clarke's Bible Commentary - Mark 4:29
Verse 29. He putteth in the sickle] apostellei, he sendeth out the sickle, i.e. the reapers; the instrument, by a metonomy, being put for the persons who use it. This is a common figure. It has been supposed that our Lord intimates here that, as soon as a soul is made completely holy, it is taken into the kingdom of God. But certainly the parable does not say so. When the corn is ripe, it is reaped for the benefit of him who sowed it; for it can be of little or no use till it be ripe: so when a soul is saved from all sin, it is capable of being fully employed in the work of the Lord: it is then, and not till then, fully fitted for the Master's use. God saves men to the uttermost, that they may here perfectly love him, and worthily magnify his name. To take them away the moment they are capable of doing this, would be, so far, to deprive the world and the Church of the manifestation of the glory of his grace. "But the text says, he immediately sendeth out the sickle; and this means that the person dies, and is taken into glory, as soon as he is fit for it." No, for there may be millions of cases, where, though to die would be gain, yet to live may be far better for the Church, and for an increase of the life of Christ to the soul. See Philippians i. 21, 24. Besides, if we attempt to make the parable speak here what seems to be implied in the letter, then we may say, with equal propriety, that Christ sleeps and wakes alternately; and that his own grace grows, he knows not how, in the heart in which he has planted it.
John Gill's Bible Commentary
Ver. 29. But when the fruit is brought forth , etc..] Unto perfection, and is fully ripe; signifying that when grace is brought to maturity, and faith is performed with power, and the good work begun is perfected; then, as the husbandman, immediately he putteth the sickle ; and cuts it down, and gathers it in; because the harvest is come ; at death or at the end of the world, which the harvest represents: when all the elect of God are called by grace, and grace in them is brought to its perfection, and they have brought forth all the fruit they were ordained to bear, they will then be all gathered in; either by Christ himself who comes into his garden, and gathers his lilies by death; or by the angels, the reapers, at the close of time, who will gather the elect from the four winds; or the ministers of the Gospel, who shall come again with joy, bringing their sheaves with them; being able to observe with pleasure a greater increase, and more fruit of their labours, than they knew of, or expected.
Matthew Henry Commentary
Verses 21-34 - These declarations were intended to call the attention of the disciple to the word of Christ. By his thus instructing them, they were mad able to instruct others; as candles are lighted, not to be covered, but to be placed on a candlestick, that they may give light to a room. Thi parable of the good seed, shows the manner in which the kingdom of God makes progress in the world. Let but the word of Christ have the plac it ought to have in a soul, and it will show itself in a goo conversation. It grows gradually: first the blade; then the ear; afte that the full corn in the ear. When it is sprung up, it will go forward. The work of grace in the soul is, at first, but the day of small things; yet it has mighty products even now, while it is in it growth; but what will there be when it is perfected in heaven!

Vincent's NT Word Studies
29. Is brought forth (paradoi). This rendering cannot be correct, for the verb is active, not passive, meaning to deliver up. Hence it is usually explained, shall have delivered itself up to harvest; which is stilted and artificial. Rev. is ripe, is a free rendering from the margin of A.V. It is, perhaps, better to explain, as Meyer does, whose rendering is adopted by Rev. in margin: When the fruit shall have allowed, i.e., shall have admitted of being harvested. Xenophon and Herodotus use the word in the sense of permit or allow; and an exact parallel to this occurs in the historian Polybius (xxii., 24, 9): "When the season permitted" (paradidoushv).Putteth in (apostellei). Lit., sendeth forth. So Rev. in margin. The rendering, putteth in, misses the figure. The verb is the same as that used of sending forth the apostles to reap the harvest of souls. See especially John iv. 38: "I sent (apesteila) you to reap."
Robertson's NT Word Studies
4:29 {Is ripe} (paradoi, second aorist subjunctive with hotan). Whenever the fruit yields itself or permits. {Putteth forth} (apostellei). Sends forth the sickle. The word for _apostle_ comes from this verb. See #Joh 4:38: "I sent you forth to reap" (ego apesteila humas qerizein). Sickle (drepanon) here by metonymy stands for the reapers who use it when the harvest stands ready for it (paresteken, stands by the side, present perfect indicative).
