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.

Steven Lee "Luke" Lukather (born October 21, 1957) is an American guitarist, singer, songwriter, arranger, and record producer best known for his work with the rock band Toto. A prolific session musician, Lukather has recorded guitar tracks for more than 1,500 albums representing a broad array of artists and genres. He has also contributed to albums and hit singles as a songwriter, arranger, and producer. Lukather has released six solo studio albums and is working on his seventh.

In 1976, when Lukather was nineteen years old, he was invited by his high school friends David Paich and the Porcaro brothers Steve and Jeff to join them in forming their band, Toto. He remained a member until the band split up in 2008, and has been involved in their periodic reunion tours. Lukather's reputation as a guitarist and his association with Paich and Jeff Porcaro, who also became established artists, allowed him to secure a solid flow of session work in the 1970s and 1980s. Lukather has been nominated for twelve Grammy awards, and has won five. While his work with Toto was predominantly based on pop rock music and his solo work ventures into progressive rock and hard rock, many of Lukather's side-projects are focused on jazz fusion. He held a long-time collaboration with jazz guitarist Larry Carlton that produced a Grammy-winning live album, and he was a member of the jazz fusion band Los Lobotomys, a collaboration of notable session musicians.

In 1981, Steinberg wrote "Precious Time", the title track for Pat Benatar's Precious Time album; he also penned "I'm Gonna Follow You", which appeared on her second album Crimes of Passion the previous year. His band Billy Thermal included "I'm Gonna Follow You" as well as "How Do I Make You?" on their EP released by Planet Records in 1979.
