Matthew 1:25 tells us that Joseph did not have marital relations with Mary before she gave birth, and that he named the child Jesus. The verse is the narrator’s own statement, written by Matthew to explain how Joseph responded to the angel’s message in the verses just before it. It is addressed to readers of the Gospel who needed to understand that Jesus’ birth was miraculous and that Joseph was obedient to God’s instruction.
And didn’t know her sexually until she had given birth to her firstborn son. He named him Jesus.

What Matthew 1:25 Means
The phrase “didn’t know her sexually until she had given birth” describes a period of restraint. Joseph took Mary into his home as his wife, as the angel had told him to do, but he did not share a marriage bed with her until after the child was born. The verse says nothing about what happened afterward, so it does not settle questions about Mary’s later life. It only tells us about this window of time, and it shows that the birth happened without any human father.
The second sentence is simple. Joseph gives the child the name Jesus, which the angel had already announced in the verses before. Naming a child in the ancient world was a way of claiming him as one’s own, so Joseph’s act is a quiet acceptance of responsibility for a son who was not his biologically. The verse does not promise that every obedient person will be protected from confusion, but it does show a man trusting God’s word when the situation made little sense.
The Context of Matthew 1:25
The Gospel of Matthew was written for a community that knew the Hebrew Scriptures well, and its author often points back to them to show that Jesus fulfills what God promised. Verses 22 and 23 quote the prophet Isaiah, and the name Immanuel, meaning “God with us,” frames the whole scene. Matthew 1:25 completes that quotation by showing the child’s birth and naming, which is why the verse matters so much to the story.
Just before this verse, Joseph wakes from his sleep and does exactly what the angel commanded. The verse therefore reads as the next step in a narrative of quiet obedience. Seen this way, the restraint and the naming are not isolated details but part of a larger picture of a righteous man who listens to God and acts on what he hears.
Key Phrases in Matthew 1:25
Matthew 1:21
She shall give birth to a son. You shall call his name Jesus, for it is he who shall save his people from their sins.”
(WEB)
This verse comes just before the passage and gives the angel’s reason for the name Jesus. Reading it alongside Matthew 1:25 shows that the naming was not arbitrary but tied to the promise that he would save his people from their sins.
Isaiah 7:14
Therefore the Lord himself will give you a sign. Behold, the virgin will conceive, and bear a son, and shall call his name Immanuel.
(WEB)
This is the prophecy Matthew quotes in the verses leading up to our passage. Reading the original promise helps you see why Matthew considered the birth of Jesus the fulfillment of God’s word spoken centuries earlier.
A Short Prayer From Matthew 1:25
Father, thank you that you keep your promises even when they arrive in ways we do not expect. Help me to trust your word when I cannot see the whole picture, the way Joseph did when he woke from his sleep and obeyed. Teach me to listen closely for your voice and to act on what I hear, even when others around me do not understand. Give me a heart that is willing to receive the people and responsibilities you place in my life. Thank you for being God with us. Amen.
