Grandfather
Verse 3
The advice did not begin with the father, who is writing the poem. The father learned this lesson from his own father. The lesson is good, because it is ancient. Grandfather followed this advice. And he saw that it was good advice. This is why he taught it to the boy’s father. The father has lived by this advice too. So now he teaches it to his own sons.
The words of verse 3 speak about the father’s childhood. These words suggest a loving home. The father was grandmother’s only child, so he was close to her. Grandfather taught his lessons with love to his little child.
Verse 4
The grandfather began his lessons in the same way as the poet. The grandfather also emphasised that the lesson was important.
Today, many people say that things are important. A salesman will say that his advice is important. This is because the salesman wants us to buy his products. We can doubt salesmen and politicians. But we must not doubt God’s word. The Book of Proverbs repeats its advice, because wisdom really is important.
This suggests Solomon was once an only child. Or, at least, that he benefitted from one-on-one time with his parents. He was David's son, and Bathsheba was his mother. Later, he had three brothers. First Chronicles 3:1–9 lists David's sons. Verse 5 gives the names of the sons who were born to him and Bathsheba. They were Shimea, Shobab, Nathan, and Solomon. Scripture does not always list children in their birth order, and often omits names entirely. The fact that Solomon is listed last as a child of David and Bathsheba might simply be for emphasis, not necessarily that he was the last one born, especially given what we read in 2 Samuel 12. Either way, it seems Solomon enjoyed a special place in his parents' love that afforded him exposure to the kind of teaching that would make him wise.
Parents should not become so busy that they have little or no time to devote to the spiritual training of their children. Those who teach their children well will be remembered fondly by their children when their children are adults. Joseph and Mary likely spent quality time with the boy Jesus, because Luke 2:52 tells us "Jesus increased in wisdom and in stature and in favor with God and man."
