Kommentar zu Bereschit 2:5

טרם יהיה בארץ WAS NOT YET IN THE EARTH — Wherever טרם occurs in the Scriptures it means “not yet” and does not mean “before”. It cannot be made into a verbal form, saying הטרים as one says הקדים (verbal form of קדם) and this passage proves that this is the meaning and not "before" as well as another (Exodus 9:30), כי טרם תראון “that ye do not yet fear the Lord”. Therefore you must explain this verse also thus: “No plant of the field was yet in the earth” at the time when the creation of the world was completed on the sixth day before man was created, and וכל עשב השדה טרם יצמח means “and every herb of the field had not yet grown”. But as regards the third day of creation about which it is written “The earth brought forth etc.” this does not signify that they came forth above the ground but that they remained at the opening of the ground (i. e. just below the surface) until the sixth day (Chullin 60a).

AND EVERY SHRUB OF THE FIELD. In the opinion of our Rabbis in Bereshith Rabbah,²⁸¹See Bereshith Rabbah 12:4 for a similar text. See also Rashi here. [every herb of the field created] on the third day [did not come forth above the ground but] they remained just below the surface of the earth, and on the sixth day they grew after He caused rain to fall on them.
In my opinion, in accordance with the plain meaning of Scripture, on the third day the earth did bring forth the grass and the fruit trees in their full-grown stature and quality as He commanded concerning them. And now Scripture tells that there was no one to plant and sow them for future purposes, and the earth would not produce until a mist would come up from it and water it, and man was formed who would work it — to seed, to plant, and to guard. This is the meaning of the shrub of the field… had not yet grown. It does not say “the shrub of the ground” for only a place which is cultivated is called “field,” as in Which thou hast sown in the field²⁸²Exodus 23:16. and We will not pass through field or through vineyard.²⁸³Numbers 20:17. This is the course of the world that was to be following the six days of creation and forever after, that due to the mist the heavens will bring down rain, and due to the rains the earth will make the seeds that are sown in it to spring up.

טרם יהיה בארץ, these words emphasise that although all phenomena had been created, this referred to their potential, not to their functioning as they do nowadays. כל עשב השדה, had not yet sprouted,
