Charles H. Spurgeon on Psalms 68:30

Rebuke the wild beasts of the reeds. This is our marginal version, which is the proper one. Most modern critics consider that the lion is here intended, which frequently makes its den among reeds or brush wood. Innumerable lions wander about among the reeds and copses, on the borders of the rivers of Mesopotamia. The river Jordan was infested with them (Jer 4:7 49:19). Hence, the wild beasts of the reed may signify the Syrian kings, who often contended with David. Benjamin Boothroyd.
