to the time of the composition of the Psalm which is required by its contents. It is just the same with the paragogic i in the future in Psa 136:6. But in other respects the language is classic; and the rhythm, at the beginning softly elegiac, then more and more excited, and abounding in guttural and sibilant sounds, is so expressive that scarcely any Psalm is so easily impressed on the memory as this, which is so pictorial even in sound.

And גּם is purposely chosen instead of ו: with the sitting down in the solitude of the river's banks weeping immediately came on; when the natural scenery around contrasted so strongly with that of their native land, the remembrance of Zion only forced itself upon them all the more powerfully, and the pain at the isolation from their home would have all the freer course where no hostilely observant eyes were present to suppress it. The willow (צפצפה) and viburnum, those trees which are associated with flowing water in hot low-lying districts, are indigenous in the richly watered lowlands of Babylonia. ערב (ערבה), if one and the same with Arab. grb, is not the willow, least of all the weeping-willow, which is
