“Lo, children are an heritage of the LORD,
and the fruit of the womb is His reward.
As arrows are in the hand of a mighty man,
so are children of the youth.
Happy is the man that has his quiver full of them.
They shall not be ashamed,
but they shall speak with the enemies in the gate.”
By “speaking with the enemies in the gate,” David meant that those children had matured in wisdom and integrity and faith to be able to fearlessly withstand the enemies of righteousness at the city’s weakest point. It is a wonderful feeling for parents to see their child grow up and confront the enemies of righteousness, and deny the wicked access into the city.
