Then thou shalt see, and flow together, and thine heart shall fear, and be enlarged; because the abundance of the sea shall be converted unto thee, the forces of the Gentiles shall come unto thee. (Isaiah 60:5)
Heb. nahar, which also means “to beam [with joy].” The context favors this meaning.
Fear.
Literally, “tremble,” that is, with joy (see Jer. 33:9). Israel would thrill at the realization of her glorious destiny. Dead Sea scroll 1QIs omits the word translated “fear.”
The abundance of the sea.
An allusion to the international sea trade of Isaiah’s day, which brought wealth to those who engaged in it.
The forces.
Heb. chel, “wealth.” Converted Gentiles would make generous contributions to advance and thus hasten the proclamation of the gospel (see p. 29).
