Matthew Poole and continuators on Matthew 1:21

21 And she shall bring forth a Son, and thou shalt call his name Jesus: for he shall save his People from their sins.

When the usual time of Women is accomplished, she shall bring forth a Son, and thou shalt call his name Iesus. He shall not be thy Natural Son, but he shall be her Son, not begot by thee, but brought forth by her, so, Flesh of her Flesh, His namë shall be called Iesus by thee, or by his Mother. It is the Will of God thou should'st give him that Name. For he shall save his People from their Sins. It was the Custom of the Iews (Gods Ancient People) to give Names to their Children, either expressive of the Mercy which God had shewed them in giving them their Children, or of the Duty which their Children did owe unto God. This name was given by God, expressing the Mercy of God to his People, in giving them this Child. For, he shall save his People from their Sins (saith the Angel) Iesus comes from an Hebrew word, which signifies Salvation. Ioshua had his Name from the [illegible: 1 word] word, because he was to be a Temporal Saviour to save the Iews, the whole Body of the Iews from the Canaanites their Enemies. This Iesus was to save his People, all that should believe in his Name, whether Iews or Gentiles from their Sins: Hereby the Angel hints the mistake of the Iews, in thinking the Messias should be a Temporal Saviour, who should save the Iews from their Enemies, minding them, that he was to save them not from their Bodily but Spiritual Enemies, from their Sins: The Guilt of them, and the Power of them, and from the eternal Danger of them, and he alone should do it; Acts 4.12. There is no other Name under Heaven given amongst men, neither is there Salvation in any other.
