A personal name appearing in 1 Chronicles 24:24 with a Ketiv/Qere variant: the written text (Ketiv) has Shamor, while the traditional reading (Qere) has Shamir. The individual is identified as a Levite in the divisions of temple service during David's reign. The Septuagint offers varied transliterations (Samer, Semmer), showing ancient uncertainty about the correct form. The name Shamir can mean 'thorn' or 'flint,' or it may be related to 'guarding' (from the root shamar). The textual variant is minor—likely a scribal issue with vowel pointing—and does not affect the individual's role or identity. Both forms appear in the same verse, creating a unique case where Ketiv and Qere are both preserved as glosses.
