Matthew 5:9 is the ninth verse of the fifth chapter of the Gospel of Matthew in the New Testament. It is the seventh verse of the Sermon on the Mount, and also seventh of what are known as the Beatitudes.
In the King James Version of the Bible the text reads:
The New International Version translates the passage as:

The word peacemakers does not imply pacifism, unlike later sections of the sermon. It does not refer to those who do not fight, but those who actively bring conflict to an end. Hill notes that peacemakers is a rarely used word in the period, and that it was most commonly used to refer to Roman Emperors who had brought peace. As such this verse formed the heart of St. Augustine's argument in favour of just war, arguing that a war that brought about greater peace was justified. Clark notes that the first century was in the middle of the Pax Romana and actual wars were rare and that the verse may have referred to disputes within the community, rather than actual wars. Hare agrees that this verse isn't praise of the Pax Romana, but rather a reflection that the Roman forces had not brought harmony or cooperation and that such things were impossible to impose by force.
What precisely the author of Matthew was advocating in this verse is unclear. Davies and Allison note that it can be read as supporting those who are at peace with God, but they state that most scholars believe it more likely refers to those who are reconciled with other people, a theme which recurs in Matthew. Boring believes this verse is a rejection of the proto-Zealots and a defence of why the Christian community did not participate in the Great Jewish Revolt.
Martin Luther and other early Protestant translators of the Bible preferred the translation "children of God," because they wanted to avoid any confusion as to whether Jesus was the only Son of God. "Sons of God" is, however, the more accurate translation and is used by most modern Bible translations. In several places the Gospel makes clear that the population in general can be called sons of God and Jesus frequently refers to God as "our Father" or "your Father."
