What does Psalm 128:3 mean?
This continues a description of blessings which come from faithful obedience to the Lord (Psalm 128:1–2). As a nation, Israel was promised blessings or disaster, depending on their obedience to the Lord (Deuteronomy 30:15–18). This does not mean that following God is a guaranteed path to prosperity (John 16:33). For most people, however, following God's will is much more likely to bring success than defying Him (Proverbs 9:10–11; 11:3–8; 14:27).In the ancient world, fertility was directly associated with divine favor. This was an era without social services or retirement. A person's children were their source of support in old age. They were also the primary legacy which the parents left behind. Women, in particular, were deeply ashamed by an inability to have children. The stories of women like Hannah (1 Samuel 1:2, 27) demonstrate these struggles. Here, one of the blessings offered to Israel is a wife like a "fruitful vine" and many children. This was seen as a great gift (Psalm 127:4–5).
