273. That 'thorn and thistle' means curse and vastation is clear from the fact that 'harvest' and 'fruitful tree' mean the opposite, namely blessings and increases. It is clear from the Word that thorn, thistle, brier, bramble, and nettle have such meanings, as in Hosea,

Behold, they have gone away on account of the vastation; Egypt will gather them, Moph ¹ will bury them, their precious things of silver. The nettle will inherit them, the bramble will be in their tents. Hosea 9:6.

Here 'Egypt' and 'Moph' ¹ stand for people who rely on themselves and on their own factual knowledge to be wise in Divine matters. In the same prophet,

The high places of Aven, the sin of Israel, will be destroyed. Thorn and thistle will grow up on their altars. Hosea 10:8.

Here 'the high places of Aven' stands for self-love, 'thorn and thistle on their altars' for profanation. In Isaiah,

They are smiting their breasts for the pleasant fields, for the fruitful vine; for over the ground of My people the spiky thorn will come up. Isaiah 32:12-13.

And in Ezekiel,

No more will there be for the house of Israel a pricking brier and a painful thorn from all those surrounding them. Ezekiel 28:24.

Fußnoten:

Like so many common verbs, the meaning of "know" in the Bible is varied and dependent on context. And in some cases -- when it is connected to ideas or objects -- its spiritual meaning and natural meaning are essentially the same. When the Bible talks about people knowing each other and especially when it talks about the Lord knowing people, the meaning has more to do with the states of love within people than it does with any factual knowledge. This makes sense if you think about it. When we really "know" somebody, what we mean is that we know what kind of person they are, what their motivations are, what they love, what they hate, what makes them tick. Those things are far more important than knowing their parents' names, where they were born or what year they graduated from school. Most often then, especially applied to people, "knowing" has to do with the perceptions we have about other people's loves and the conjunction that can exist between those with similar loves, not just a collection of facts.
