[2] Because 'ploughing' had this meaning people in the representative Church were forbidden 'to plough with an ox and an ass together', Deut 22:10. They would never have been forbidden to do this if there had not been some cause of a more internal nature, thus a cause existing in the spiritual world. Without it what would have been wrong with the two ploughing together? And what value would such a law have in the Word? That cause of a more internal nature, a cause existing in the spiritual world, is that 'ploughing with an ox' means good within the natural, and 'ploughing with an ass' means the truth there, 'an ass' being truth contained in factual knowledge, thus truth within the natural, see 5492, 5741. The more internal or spiritual cause behind the existence of this prohibition was that the angels could not have a separate idea of good and truth. The two must be joined together and make one. For this reason the angels were unwilling to see any kind of ploughing done by an ox and an ass. Celestial angels refuse even to think about truth separate from good, for all truth with them exists within good, so that also for them truth is good. It was for the same reason that people were also forbidden to wear a garment made from a mixture of wool and linen, Deut 22:11; for 'wool' meant good, and 'linen' truth.

[3] The fact that 'ploughing', also 'harrowing', 'sowing', and 'reaping', mean the kinds of activities that are connected with good and the truth that goes with it is clear in Hosea,

I will make Ephraim ride, Judah will plough, Jacob will harrow for him. Sow for yourselves in keeping with righteousness, reap in keeping with godliness, break up 'your fallow ground; and it is time to seek Jehovah, until He comes and teaches righteousness. Hosea 10:11, 12.

'Riding' is used in reference to Ephraim because 'riding' means having the use of an understanding, 'Ephraim' being the Church's gift of understanding. But 'ploughing' is used in reference to Judah because 'Judah' is the good which exists in the Church.

[4] In Amos,

Will horses run upon the rock? Will one plough with oxen? in that you have turned judgement into poison and the fruit of righteousness into wormwood. Amos 6:11, 12.

'Will horses run upon the rock?' stands for Will there be any understanding of the truth of faith? For 'rock' in the spiritual sense is faith, Preface to Genesis 22, while 'horses' means the powers of understanding, 2761, 2762, 3217, 5321. 'Will one plough with oxen?' stands for Will there be any doing of good? For 'oxen' means good in the natural, see 2180, 2566, 2781. The fact that no doing of it was possible is meant by the words that follow - 'because you have turned judgement into poison'.

[5] In Luke,

Jesus said, No one putting his hand to the plough, and looking back, is fit for the kingdom of God. Luke 9:62.

These words have the same meaning as those spoken by the Lord in Matthew,

Let him who is on the housetop not go down to take anything out of his house; and let him who is in the field not turn back to take his clothes. Matt 24:17, 18.

The meaning of these words is that a person governed by good should not depart from it and resort to matters of doctrine concerning faith; see 7652, where those words spoken by the Lord have been explained. Thus one who puts his hand to the plough' is a person governed by good; but 'looking back' means someone who then looks to matters of doctrine concerning faith and in so doing forsakes good. This explains why Elijah was displeased with Elisha who, ploughing in the field when he received his call, asked whether he might first kiss his father and mother; for Elijah said,

Go away; go back again; for what have I done to you? 1 Kings 19:19-21.

In the contrary sense 'ploughing' means evil that destroys good, and so means a laying waste, as in Jeremiah,

Zion will be ploughed [like] a field, and Jerusalem will be heaps, and the mountain of the house [will be turned] into the heights of the forest. Jer. 26:18; Micah 3:12.
