Yahweh continues speaking about Jerusalem as if it were a mother. (See: Isaiah 66:7)

like a river…like an overflowing stream

This means God will cause the people of the nations to bring a very large amount of riches, which will be permanent like a river and abundant. (See: rc://en/ta/man/translate/figs-simile)

You will nurse at her side, be carried in her arms, and be dandled on her knees

This means Jerusalem will be a place of safety and comfort for God's people. (See: rc://en/ta/man/translate/figs-metaphor)

AT: "so I will comfort you in Jerusalem"
