Thus saith the LORD, The labour of Egypt, and merchandise of Ethiopia and of the Sabeans, men of stature, shall come over unto thee, and they shall be thine: they shall come after thee; in chains they shall come over, and they shall fall down unto thee, they shall make supplication unto thee, saying, Surely God is in thee; and there is none else, there is no God.
The labour of Egypt, and merchandise of Ethiopia and of the Sabeans ... shall come over unto thee. The language literally and primarily alludes to Egypt, Ethiopia, and Seba being given to Cyrus as a ransom in lieu of Israel, whom he restored (Isaiah 43:3), but mainly and fully describes the gathering in of the Gentiles to Israel (Acts 2:10-11; Acts 8:27-38), especially at Israel's future restoration (Isaiah 2:2; Isaiah 14:1-2; Isaiah 19:18-22; Isaiah 60:3-14; Isaiah 49:23; Psalms 68:31; Psalms 72:10-11).
Labour - wealth acquired by labour (Jeremiah 3:24).
Sabeans, men of stature - the men of Meroe, in Upper Egypt. Herodotus (3: 20) calls the Ethiopians 'the tallest of men' (note, Isaiah 18:2; 1 Chronicles 11:23).
Thee - Jerusalem, ("my city," Isaiah 45:13).
In chains - (Psalms 149:8; Zechariah 14:12-19; "the saints shall judge the world," 1 Corinthians 6:2; and 'rule the nations with a rod of iron,' Revelation 2:26-27). The "chains," in the case of the obedient, shall be the easy yoke of Messiah; as "the sword of the Spirit" also is saving to the believer, condemnatory to the unbeliever (John 12:48; Hebrews 4:12; Revelation 19:15).
They shall make supplication unto thee (saying) Surely God (is) in thee (Jeremiah 3:17; Jeremiah 3:19) They shall make supplication unto thee, (saying), Surely God (is) in thee - (Jeremiah 3:17-19).
