The birth of a new baby was often announced in the Newspaper, or Church Notices, this is helpful to me as a genealogist, but it usually comes after the safe delivery of the child.

The birth of 8 children was foretold in the Bible before they happened and 7 of them God named. Names are very significant to God. But only 4 times in the Bible has a child's birth been foretold by an angel to the parents. Twice in the Old Testament and twice in the New Testament. Most of the children God "sent" had their birth announced by Prophets. But at the time of the Birth of Jesus and his cousin, John the Baptist, it was like God had fallen silent - there had been no prophet for 400 years.

The nation of Israel was living under the heel of the Roman Empire, although the Romans officially saw them as an ally at this point, it was a difficult situation for the Jewish rulers – balancing on a tightrope over a deep chasm, trying to play the neutral ally and fearful of those with conquest in mind. It was a dangerous sort of time to be born as a coming King. But God had already announced the birth, it had been foretold hundreds of years in advance, the Prophet Daniel telling 'when' and the prophet Micah telling 'where'.

So you are to know and have insight that from the going out of a word to restore and rebuild Jerusalem* until Messiah the Prince, there will be seven weeks and sixty-two weeks; it will be restored and rebuilt, with plaza and moat, even in times of distress. - Daniel 9:25

So from the start of the second Temple which took place in Nisan (March/April) of 444 BC., till 7 weeks (Litural meaning 'groups of 7'), so 7x7=49 years, + 62 groups of 7 = 434 years so a total of 483 years from the start of the second Temple. That would mean the Messiah would be born around 6 BC. History does not record anyone, other than Yeshua (Jesus), who was from that time period and claimed to be the Messiah.

But as for you, Bethlehem Ephrathah, Too little to be among the clans of Judah, From you One will go forth for Me to be ruler in Israel. His goings forth are from everlasting, From the ancient days.” - Micah 5:2

When the time came God quietly sent the Archangel Gabriel. God keeps his promises, and I believe he still quietly sends angels when we pray.
