The messiah ben Joseph is most likely Joseph Smith. He's the prophet, the latter day Joseph, who prepares the way for the return of Christ, the Messiah ben David and His millenial reign. Joseph Smith is a direct descendant of the Biblical Joseph, Jesus a direct descendant of David.
It is likely the daily sacrifice of two lambs at the temple in ancient Israel, one at sunrise and the other at sunset, were symbolic of the martydom of Jesus at the meridian of time which is sunrise on the Hebrew calendar and the martydom of Joseph Smith on June 27, 1844 at about 5 pm. There are several clues this is the case.
Joseph Smith martydom date was 10 tammuz on the Hebrew calendar, which is the day tied to the fall of Jerusalem and so relates to the destruction of the temple and the end of the daily sacrifice. Fitting if Joseph was who the sunset sacrificial lamb in the daily sacrifice at the temple was symbolic of.
The Old Testament prophet Daniel gives a prophecy that mentions the daily sacrifice and gives clues to two dates that people from Isaac Newton to the 19th century Seventh Day Adventists had calculated were 33 AD and 1844 AD. So how does 33 AD and 1844 AD relate to the two lambs sacrificed daily at the temple? It's the two martydom dates of two prophets that these two lambs are symbolic of. Daniel ch 9:
"Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks"
This fits Jesus atoning for the sins of mankind and has been calculated to be 33 AD. Daniel then ties the return of the sacrifices ie the return of the temple to a future date when the "sanctuary" will be "cleansed". This date in the prophecy has been calculated by many to be1844 AD. The 19th century Seventh Day Adventists thought the "sanctuary" being "cleansed" meant the cleansing of the earth by fire at the Second Coming and many of them sold their possessions and was looking for Christ's return in 1844. But something else happened in 1844, and that was the martydom of Joseph and his brother Hyrum. Now how was the "sanctuary cleansed" ie the temple cleansed in ancient Israel? On the Day of Atonement on the Hebrew Calendar the high priest sacriced a bull and a goat to cleanse the temple. The day of June 27, 1844 Joseph and Hyrum were martryed (10 Tammuz on the Hebrew Calendar). Besides this date being linked to the Fall of Jerusalem, 10 Tammuz is also one of four Day of Atonement on the Hebrew calendar, the 10th day of the 1st, 4th, 7th, and 10th months. They are seasonal markers, with a Day of Atonement in the Spring, Summer, Fall, and Winter. Another perfect bullseye if Joseph is being represented as the sunset lamb of the daily sacrifice, and the bull in the temple cleansing sacrifice on the Day of Atonement. The bull is symbolic of the tribe of Joseph.
Joseph Smith was also born on the winter solstice on the Hebrew Calendar. So he was born and martyred on seasonal markers on the Hebrew Calendar. His martydom date was also his mother's birthdate on the Hebrew Calendar.
According to Jewish sources the messiah ben Joseph is tied to the return of the Jews to Israel. Joseph Smith received the keys to the gathering of Israel from Moses in the Kirtland temple
Symbolism of Passover , and in 1841 sent Orson Hyde to the land of Israel to dedicate it for the return of the Jews. The following is his dedicatory prayer on the mount of olives:

"I am going like a*lamb*to the slaughter; but I am calm as a summer’s morning; I have a*conscience*void*of offense towards God, and towards all men.*I shall die innocent, and it shall yet be said of me—he was murdered in cold blood.”
