This verse is parenthetical. The covenant of promise was not "spoken" (so Greek for "made") to Abraham alone, but "to Abraham and his seed"; to the latter especially; and this means Christ (and that which is inseparable from Him, the literal Israel, and the spiritual, His body, the Church). Christ not having come when the law was given, the covenant could not have been then fulfilled, but awaited the coming of Him, the Seed, to whom it was spoken. promises--plural, because the same promise was often repeated (Gen 12:3, Gen 12:7; Gen 15:5, Gen 15:18; Gen 17:7; Gen 22:18), and because it involved many things; earthly blessings to the literal children of Abraham in Canaan, and spiritual and heavenly blessings to his spiritual children; but both promised to Christ, "the Seed" and representative Head of the literal and spiritual Israel alike. In the spiritual seed there is no distinction of Jew or Greek; but to the literal seed, the promises still in part remain to be fulfilled (Rom 11:26). The covenant was not made with "many" seeds (which if there had been, a pretext might exist for supposing there was one seed before the law, another under the law; and that those sprung from one seed, say the Jewish, are admitted on different terms, and with a higher degree of acceptability, than those sprung from the Gentile seed), but with the one seed; therefore, the promise that in Him "all the families of the earth shall be blessed" (Gen 12:3), joins in this one Seed, Christ, Jew and Gentile, as fellow heirs on the same terms of acceptability, namely, by grace through faith (Rom 4:13); not to some by promise, to others by the law, but to all alike, circumcised and uncircumcised, constituting but one seed in Christ (Rom 4:16). The law, on the other hand, contemplates the Jews and Gent…

The apostle in this chapter, I. Reproves the Galatians for their folly, in suffering themselves to be drawn away from the faith of the gospel, and endeavours, from several considerations, to impress them with a sense of it. II. He proves the doctrine which he had reproved them for departing from - that of justification by faith without the works of the law, 1. From the example of Abraham's justification. 2. From the nature and tenour of the law. 3. From the express testimony of the Old Testament; and, 4. From the stability of the covenant of God with Abraham. Lest any should hereupon say, "Wherefore then serveth the law?" he answers, (1.) It was added because of transgressions. (2.) It was given to convince the world of the necessity of a Saviour. (3.) It was designed as a schoolmaster, to bring us to Christ. And then he concludes the chapter by acquainting us with the privilege of Christians under the gospel state.

3:16 The promises to Abraham were primarily inherited by Abraham and his child (literally his seed)—the promised Messiah, the ultimate descendant of Abraham. “Seed” can refer to a single descendant or to many descendants (see Gen 12:7; 13:15). Although the promise has a plural sense (see Gal 3:29; Gen 13:15-16; 15:5-6; 17:7-8), this singular noun points to the one descendant, Christ, who completely fulfilled the promise. The heirs of the promise are not Jacob’s physical children, but the spiritual children of Christ by the Spirit through faith.
