Isaiah 6:13. “But yet in it shall be a tenth, and it shall return, and shall be eaten: as a teil tree, and as an oak, whose substance is in them, when they cast their leaves: so the holy seed shall be the substance thereof.”
There is always a “remnant” of faithful ones in the nation, and God shows His mercy to this remnant. “It shall again be eaten up”: It too will suffer, as in a purifying fire (Mal. 3:3).This verse is fulfilled by those who returned from captivity by the decree of Cyrus, recorded in Ezra and Nehemiah. It will be fulfilled again in “the time of Jacob’s trouble” under the Antichrist (Jer. 30:7).

(an old name for the lime-tree, the tilia), Isaiah 6:13 , the terebinth, or turpentine-tree, the Pistacia terebinthus of botanists. The Hebrew word here used (elah) is rendered oak (q.v.) in Genesis 35:4 ; Judges 6:11Judges 6:19 ; Isaiah 1:29 , etc. In Isaiah 61:3 it is rendered in the plural “trees;” Hosea 4:13 , “elm” (RSV, “terebinth”). Hosea 4:13 , “elm” (RSV, “terebinth”). In 1Sam 17:2,19it is taken as a proper name, “Elah” (RSV marg., “terebinth”).
“The terebinth of Mamre, or its lineal successor, remained from the days of Abraham till the fourth century of the Christian era, and on its site Constantine erected a Christian church, the ruins of which still remain.”
This tree “is seldom seen in clumps or groves, never in forests, but stands isolated and weird-like in some bare ravine or on a hill-side where nothing else towers above the low brushwood” (Tristram).
What a perfect picture of the remnant, for the most part standing alone, and enduring across time. Even after its branches are cut off and nothing but a stump remains, there is still life. Shoots and leaves will spring out of the stump. Again this description of “a holy seed) applies both to Judah’s return under Cyrus, as well as during the time of the Antichrist. The nation, consisting of the remnant, will revive and be glorified under Messiah, the Deliverer (see 11:1.)
