Acts 15:14

Simeon hath declared how God at the first did visit the
Gentiles
James begins with taking notice of Peter's speech, and agrees to it, and confirms it; for by Simeon is not meant, as some have thought, the Simeon that took Christ in his arms, ( Luke 2:25 ) who had been dead long ago; but Simon Peter, who had spoken before. Simon and Simeon are one and the same name; the former is only a contraction of the latter in the Syriac language; Simeon was his pure Hebrew name, and James speaking to an assembly of Hebrews, uses it; and observes, that he had given a very clear and distinct narrative, how God at the first preaching of the Gospel, quickly after the day of Pentecost, was pleased to look upon the Gentiles, and show favour to them, and visit them in a way of grace and mercy, by sending the Gospel to them, and his Spirit to make it effectual: this was a gracious visit; he came and looked upon them, quickened them, and spoke comfortably to them, and bestowed special favours upon them; the set time for such a visit being come: the Arabic version renders it, "how God first promised"; referring to the promises concerning the calling of the Gentiles, which James afterwards confirms by citing a passage out of the prophets to the same purpose: the Syriac version, "how God began to choose out of the Gentiles": that is, by calling them by his grace; and the Ethiopic version, "how God first had mercy on the Gentiles"; who before had not obtained mercy:

to take out of them a people for his name;
for himself, for his own glory, to call upon his name, and to be called by his name, to bear his name, and support his Gospel, cause and interest: the distinguishing grace of God may be seen herein; it was grace to visit them, to look upon them, when for many hundreds of years he had overlooked them, he had taken no notice of them; and it was distinguishing grace to take some out of them, to be a special and peculiar people to himself; to separate them from the rest by his powerful and efficacious grace, and form them into a church state, that they might show forth his praise and glorify him.
