Charles Ellicott Commentary Psalms 35:3

"Draw out also the spear, and stop the way against them that pursue me: Say unto my soul, I am thy salvation." — Psalms 35:3 (ASV)

Draw out also the spear — that is, from the sheath, which seems to have been used to guard its point. So δουροδόκη (Homer, Odyssey, i. 128).

Stop the way. — So say the Septuagint, Vulgate, and all ancient versions. Many modern scholars, however, are inclined to treat the word segor not as the imperative of a verb, but as a noun. They consider it equivalent to the Greek σάγαρις and the Latin securis, a Persian and Scythian weapon mentioned by Herodotus (i. 215, iv. 70) and Xenophon (Anabasis, iv. 4, 16). This weapon is generally thought to be a battle-axe, although some interpret it as a short curved sword or a scimitar. It is identified by Sir Henry Rawlinson with the khanjar of modern Persia, “a short curved double-edged dagger, almost universally worn.” The Bedouins of modern Egypt also use a schagur.

Adopting this rendering creates an excellent parallelism, and suits the word translated “against,” which actually means “to meet,” and suggests an attack rather than a merely passive defensive posture.
