6 And Esau seeing that his father had blessed Jacob, and had sent him into Mesopotamia of Syria, to marry a wife thence; and that after the blessing he had charged him, saying: Thou shalt not take a wife of the daughters of Chanaan:
3 That I may make thee swear by the Lord the God of heaven and earth, that thou take not a wife for my son, of the daughters of the Chanaanites, among whom I dwell:
'To proclaim' signifies exploration from influx of the Lord.
