¹ tn Or “irrigation rivers” of the Nile.

³ sn The Kebar River is mentioned in Babylonian texts from the city of Nippur in the fifth century b.c. It provided artificial irrigation from the Euphrates.

³ sn The farmer channels irrigation ditches where he wants them, where they will do the most good; so does the Lord with the king. No king is supreme; the Lord rules.

³ sn These two lines are difficult, but the general sense is that of irrigation buckets and a well-watered land. The point is that Israel will be prosperous and fruitful.

² tn Heb “with your foot” (so NASB, NLT). There is a two-fold significance to this phrase. First, Egypt had no rain so water supply depended on human efforts at irrigation. Second, the Nile was the source of irrigation waters but those waters sometimes had to be pumped into fields and gardens by foot-power, perhaps the kind of machinery (Arabic shaduf) still used by Egyptian farmers (see C. Aldred, The Egyptians, 181). Nevertheless, the translation uses “by hand,” since that expression is the more common English idiom for an activity performed by manual labor.

¹ sn The city of God is Jerusalem (see Pss 48:1-2; 87:2-3). The river’s “channels” are probably irrigation ditches vital to growing crops. Some relate the imagery to the “waters of Shiloah” (see Isa 8:6), which flowed from the Gihon spring to the pool of Siloam. In Isa 8:6-8 these waters are contrasted with the flood waters symbolizing Assyria. Even if this is the reality behind the imagery, the picture of a river flowing through Jerusalem is idealized and exaggerated. The river and irrigation ditches symbolize the peace and prosperity that the Lord provides for Jerusalem, in contrast to the havoc produced by the turbulent waters (symbolic of the nations) outside the city. Some see here an adaptation of Canaanite (or, more specifically, Jebusite) mythical traditions of rivers/springs flowing from the high god El’s dwelling place. The Songs of Zion do utilize such imagery at times (see Ps 48:2). The image of a river flowing through Zion may have inspired prophetic visions of an eschatological river flowing from the temple (see Ezek 47:1-12; Joel 3:18).

¹ sn Babylon was a city covering over a thousand acres that was surrounded by two walls, the inner one 21 feet (6.3 m) thick and the outer one 11 feet (3.3 m) thick. To provide the city further security, other walls were built to its south and east, and irrigation ditches and canals to it north and east were flooded to prevent direct access. The “fords” were crossings for the Euphrates River, which ran right through the city, and for the ditches and canals. The “reed marshes” were low-lying areas around the city where reeds grew. Burning them would deprive any fugitives of places to hide and flush out any who had already escaped.
