Lexical Definition

‎שִׁיר‎ shîyr (sheer) to sing H:V
or (the original form) שׁוּר shûwr (shoor); (1 Samuel 18:6), a primitive root (rather identical with ‎שׁוּר‎ through the idea of strolling minstrelsy)

behold (by mistake for ‎שׁוּר‎), sing(-er, -ing man, -ing woman).

1) to sing
1a) (Qal)
1a1) to sing
1a2) singer, songstresses (participle)
1b) (Polel)
1b1) to sing
1b2) singer, songstress (participle)
1c) (Hophal) to be sung
++++
In Job 36:24, the word is translated "Behold"; in modern versions, it is translated "Sing". The old translations considered the Hebrew word to be from a different root than שׁוּר hence the difference in the translations.
