David

David (/ˈdeɪvɪd/; Hebrew: דָּוִד, Modern David, Tiberian Dāwîḏ;ISO 259-3 Dawid; Arabic: داوُد‎ Dāwūd; Syriac: ܕܘܝܕ‎ Dawid; Ancient Greek: Δαυίδ; Latin: Davidus, David; Strong's: Daveed) was, according to the Books of Samuel, the second king of the United Kingdom of Israel, and according to the New Testament, an ancestor of Jesus. His life is conventionally dated to c. 1040 – 970 BCE, his reign over Judah c. 1010–970 BCE.

The Books of Samuel, 1 Kings, and 1 Chronicles are the only Old Testament sources of information on David, although the Tel Dan Stele (dated c. 850–835 BCE) contains the phrase בית דוד (bytdwd), read as "House of David", which many scholars confirm to be a likely plausible match to the existence in the mid-9th century BCE of a Judean royal dynasty called the House of David.

Depicted as a valorous warrior of great renown, and a poet and musician credited for composing much of the psalms contained in the Book of Psalms, King David is widely viewed as a righteous and effective king in battle and civil justice. He is described as a man after God's own heart in 1 Samuel 13:14 and Acts 13:22.

His sister Sara Antunes was already a public celebrity and his older brother Mickael Carreira has had a singing career since 2007.
