There. — This word in Psalms 14:5 does not appear to have a strictly definite local sense; and here may refer to time, possibly to some event, which we are not able with certainty to recover.
Arrows. — Literally, flashes. (See Note, Song of Solomon 8:6.) The image may be derived from the lightning speed of the flight of arrows, or from the custom of shooting bolts tipped with flame (see Note, Psalms 7:13), or the connection may be from the metaphor in Psalms 91:5-6, since the Hebrew word here used denotes pestilence in Habakkuk 3:5.
The shield, the sword, and the battle — Hosea 2:18 is the original of this. (Comp. Psalms 46:9.) Notice the fine poetic touch in the climactic use of battle to sum up all the weapons of war.
