Yeshayah 61:9 Meaning and Commentary

Isaiah 61:9

And their seed shall be known among the Gentiles, and their
offspring among the people
Not only the Jews will be converted as a body in the latter day, but there will be a succession of converts among them in later ages, and will be known among Christian Gentiles by their faith and love, and good works and holy conversation; and will be taken notice of and acknowledged by them as brethren, and will be famous among them for religion and godliness:

all that see them shall acknowledge them, that they are the seed which
the Lord hath blessed;
that they are the spiritual seed of Abraham, as well as his carnal seed, and are blessed with him; blessed with all spiritual blessings in Christ, with faith in him, and with every other grace.

Yeshayah 61:9 In-Context

7 Instead of your bushah (shame) ye shall have a mishneh (double [portion]); and for dishonor they shall rejoice in their chelek (portion): therefore in their land they shall possess the mishneh; simchat olam (everlasting joy) shall be unto them.

8 For I Hashem love mishpat, I hate gazel (robbery) in [obtaining] the olah (burnt offering); and I will direct their work in emes, and I will make a Brit Olam [Gn 12:1- 3; Isa 55:3] with them.

9 And their zera shall be known among the Goyim and their offspring among the Nations: all that see them shall acknowledge them, that they are the Zera Berach Hashem.

10 I will greatly rejoice in Hashem, my nefesh shall be joyful in Elohai; for He hath clothed me with the Bigdei Yesha (Garments of Salvation), He hath covered me with Me’il Tzedakah (the Robe of Righteousness) like a Choson arrays himself with splendor, and like a Kallah adorneth herself with her jewels.

11 For as Eretz bringeth forth her tzemach, and as the gan (garden) the things that are sown in it tatzmiach (causes [them] to spring forth); so Adonoi Hashem will tzedakah (righteousness) and tehillah (praise) yatzmiach (cause [them] to spring forth) before kol HaGoyim.
