As iron sharpens iron, one person sharpens another.  Proverbs 27:17

Two are better than one, because they have a good return for their labor: if either of them falls down, one can help the other up. But pity anyone who falls and has no one to help them up. Also, if two lie down together, they will keep warm. But how can one keep warm alone? Though one may be overpowered, two can defend themselves. A cord of three strands is not quickly broken.  Ecclesiastes 4:9-12

And the things you have heard me say in the presence of many witnesses entrust to reliable people who will also be qualified to teach others.  2 Timothy 2:2

Husbands, love your wives, just as Christ loved the church and gave himself up for her to make her holy, cleansing her by the washing with water through the word, and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless.  Ephesians 5:25-28

Husbands, love your wives and do not be harsh with them. Children, obey your parents in everything, for this pleases the Lord. Fathers, do not embitter your children, or they will become discouraged.  Colossians 3:19-21

Love the LORD your God with all  your heart and with all your soul and with all your strength. These commandments that I give you today are to be on your hearts. Impress them on your children. Talk about them when yo sit at home and when you walk along the road, when you lie down and when you get up.  Deuteronomy 6:5-7

... just as the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many.  Matthew 20:28

Above all else, guard your heart, for everything you do flows from it.  Proverbs 4:23
