David Luiz Moreira Marinho (born 22 April 1987), known as David Luiz, is a Brazilian footballer who plays for Chelsea in the Premier League. Primarily a central defender, he can also be deployed as a left back.

After starting out at Vitória, he moved to Benfica at the age of 19, remaining with the club five seasons (three complete). He joined Chelsea in January 2011, winning the Champions League and the FA Cup in the following season.

Born in Diadema, São Paulo, David Luiz arrived in Esporte Clube Vitória at the age of 14 after being released by São Paulo FC, and started playing as a defensive midfielder, almost leaving the club for his poor performances in that position. However, he was soon moved to central defender and adapted well.

Luiz made his official debut for Vitória in 2006, and excelled against Santa Cruz Futebol Clube for that season's Brazilian Cup, in a 2–2 draw. At the worst situation of its history, in the third division, Vitória promoted to the second division at the end of the season with Luiz's help, after finishing in second position, with the central appearing in eight of the club's last decisive nine games, scoring his only Série C goal on 3 September 2006, in a 2–0 home win against Clube Atlético do Porto.

David (Hebrew: דָּוִד, דָּוִיד, Modern David Tiberian Dāwîḏ; ISO 259-3 Dawid; Strong's Daveed; beloved; Arabic: داوود‎ or داود‎ Dāwūd) was, according to the Hebrew Bible, the second king of the United Kingdom of Israel and, according to the Gospel of Matthew and the Gospel of Luke, an ancestor of Jesus. David is seen as a major Prophet in Islamic traditions. His life is conventionally dated to c. 1040–970 BC, his reign over Judah c. 1010–1003 BC,^{[citation needed]} and his reign over the United Kingdom of Israel c. 1003–970 BC.^{[citation needed]} The Books of Samuel, 1 Kings, and 1 Chronicles are the only sources of information on David, although the Tel Dan stele records "House of David", which some take as confirmation of the existence in the mid-9th century BC of a Judean royal dynasty called the "House of David".

David is very important to Jewish, Christian and Islamic doctrine and culture. In Judaism, David, or David HaMelekh, is the King of Israel, and the Jewish people. Jewish tradition maintains that a direct descendant of David will be the Messiah. In Islam, he is known as Dawud, considered to be a prophet and the king of a nation. He is depicted as a righteous king, though not without faults, as well as an acclaimed warrior, musician, and poet, traditionally credited for composing many of the psalms contained in the Book of Psalms.
