This is not just for the husband to nourish his wife alone but his children also. You must nourish your children to the point where they are able to speak to the enemies at the gate. Where you don’t need to do things but your children has known the way of the Lord and has learn to speak the word and you can commit things to their care as they speak to the enemies at the gate. 

Psalms  127:3 Lo, CHILDREN ARE AN HERITAGE OF THE LORD: and the fruit of the womb is his reward.  

127:4 As arrows are in the hand of a mighty man; so are children of the youth.

Psalms  127:5  Happy is the man that hath his quiver full of THEM: they shall not be ashamed, BUT THEY SHALL SPEAK WITH THE ENEMIES IN THE GATE.

You see that, so you have to train them in the way of the Lord. 

Proverbs  22:6 TRAIN UP A CHILD in the way he should go: and when he is old, he will not depart from it.

It’s easy to train a child than a man that has matured, it is because such is full of knowledge and what you say will make him to disagree some times even when you are totally right. So train your  child. 

You also need to nourish your wife.

Ephesians  5:29 For no man ever yet hated his own flesh; BUT NOURISHETH AND CHERISHETH IT, EVEN AS THE LORD THE CHURCH:

Except the man is insane that he will begin to say I hate my body and then begin to cut himself. No, every man love their bodies and try to ensure nothing happens to it, because of one thing, and that one thing may be the uttermost because of people that will see his body. Though it’s always because of someone and also himself. So, your wife is referred to as your body even the church is referred to as the body of Christ. 
Colossians  1:18 AND HE IS THE HEAD OF THE BODY, THE CHURCH: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence.
You see, He also nourish His body by flooding us with revelation of His Word. We even get built up by His language. The language of the Lord. She must also be built up by your language. What language are you speaking to her? Not necessarily your dialect. Your communication. For as we speak the language of God we get built. 

Jude  1:20 But ye, beloved, building up yourselves on your most holy faith, PRAYING IN THE HOLY GHOST,

1 Corinthians  14:2 For he that speaketh in an unknown tongue speaketh not unto men, BUT UNTO GOD: for no man understandeth him; howbeit in the spirit he speaketh mysteries.

Your words must be able to build up your wife. It’s must be able to build up your family. Words are actually meant to build, especially with the right word. When building a house, it is carefully and professionally constructed. You don’t give it to novice or else you know what that means. So build your wife with right word of God, and right word from your mouth. 

Acts  20:32 And now, brethren, I commend you to God, and TO THE WORD OF HIS GRACE, WHICH IS ABLE TO BUILD YOU UP, and to give you an inheritance among all them which are sanctified.

What you build her with must be able to drive her somewhere, to the Lord and also draw her closer to you. 

AS THE HEAD LIKE CHRIST YOU NOURISH HER. 

Paul was talking about the need to hold the Head, which is Christ. 

Colossians  2:19 And not holding the Head, from which all the body by joints and bands HAVING NOURISHMENT MINISTERED, and knit together, increaseth with the increase of God.

You see what I see there, the head nourishes the body by joints and bands having nourishment ministered to them. You see that, it help to knot them together. Your children should not be confused, you must nurture them to stay together in love and not even to disobey their mother. And to increase with the increase of God. That’s beautiful, if every man or husband do like this, homes will be for the Lord, and they will be established even for it to be passed on. You need to pass it on to your children also, your sons and daughters. They must learn it. That’s how to leave good things for children.

Proverbs  13:22  A GOOD MAN LEAVETH AN INHERITANCE TO HIS CHILDREN’S CHILDREN: and the wealth of the sinner is laid up for the just.

When you train your children with all this, and also train them such  that they can give it to their children  also. You’re a blessed man.
