The Davidic line (also referred to as the House of David) (known in Hebrew as Malkhut Beit David (מלכות בית דוד) – "Kingdom of the House of David") refers to the tracing of lineage to King David referred to many times in the Hebrew Bible and in the New Testament.

According to the Tanakh upon being chosen and becoming king, the custom was anointing with holy oil poured on the head. In David's case, this was done by the prophet Samuel

In Hebrew, the anointing is called meshicha (meaning "pulling") and a king (melekh or melech in Hebrew) is referred to as a Moshiach or Messiah or a Melech HaMashiach meaning "the anointed king". The procedure of anointment, in David's case, is said to symbolize the descent of God's holiness (kedusha) upon the king and as a sign of a bond never to be broken.

Initially, David was king over the Tribe of Judah only and ruled from Hebron, but after seven and a half years, the other Israelite tribes, who found themselves leaderless after the death of Ish-bosheth chose him to be their king as well

All subsequent kings in both the ancient first united Kingdom of Israel and the later Kingdom of Judah claimed direct descent from King David to validate their claim to the throne in order to rule over the Israelite tribes.

After the death of David's son, King Solomon, the ten northern tribes of the Kingdom of Israel rejected the Davidic line, refusing to accept Solomon's son, Rehoboam, and instead chose as king Jeroboam and formed the northern Kingdom of Israel. This kingdom was eventually conquered by Assyria who exiled them, to disappear from history as The Ten Lost Tribes.
