Isaiah 18:4-7

This message by the Cushite envoys harmonized with what Yahweh had told Isaiah. Yahweh would look from His heavenly dwelling place quietly, like the shimmering heat in summer or the encroaching mist in autumn. These are figures that connote coming judgment.

He would prune the nations as a farmer pruned his grapevines and trees, but He would do it before they reached harvest time. In other words, His judging the nations would be perceived as premature. The nations would be so depopulated by this judgment that birds and beasts would feed on the remains of those judged (cf. Revelation 19:17-18).

Then the remaining representatives of all these once-powerful and aggressive nations (cf. Isaiah 18:2) would worship the Lord Almighty (cf. Psalms 68:31; Zechariah 14:16; Acts 8:26-36). They would bring their gifts to Him at Mt. Zion. This will be a time of global worship of Messiah.
