the anointed one: a person God has set apart for high office by pouring oil on him, above all the reigning king
In the Old Testament this word is a description, not yet a name. Pouring oil on a man's head was the public act that installed him into office and put him under God's authority, the way a ruler today is sworn in. Once it was done, the man was "the LORD's anointed": chosen, set apart, and so protected that to lift a hand against him was to strike at God who chose him. That is the force the word carries almost everywhere it appears.
The anointed one is most often the king, and the word clusters thickest in the story of Saul and David, where David twice refuses to kill Saul because he is "the LORD's anointed." From there it covers David and the whole line of kings after him, including the kings whose thrones collapsed in the exile. A second, narrower use names the anointed high priest, and a few striking verses stretch the word further still, to the patriarchs and even to a foreign emperor God commissions for a task.
What the word does NOT yet carry, in its own right, is the later idea of "the Messiah": one promised future deliverer. That is a development of the centuries between the Testaments. The Hebrew word names men who held real office in their own day. It supplies the raw material from which the hope of a coming anointed king would later be built, but it is not itself that title (see the cautions and the disputes).

Disputed
Who are the two anointed ones of Daniel 9:25-26? This is the hinge text for the word, the one place where it arguably begins to drift toward a future-oriented sense.
- majorityBoth figures are identifiable historical persons. The first, "an anointed one, a leader" (9:25), is most often Joshua son of Jehozadak, the first post-exilic high priest; the second, "cut off and has nothing" (9:26), is by near-unanimous critical consensus Onias III, the legitimate high priest deposed and murdered around 171 BCE, fitting a composition during the crisis under Antiochus IV.; J.

- minorityThe anointed figure or figures point forward to Jesus. This long Christian traditional reading survives in confessional interpretation but is not the historical-critical view.; A. E. Steinmann, Daniel, Concordia Commentary (Concordia, 2008)
