Where in the Bible does it say that you are to be helpers one to another?

Galatians 6:2 - Bear one another's burdens, and so fulfill the law of Christ. 1 Corinthians 12:25, 26 -that there should be no schism in the body, but that the members should have the same care for one another. And if one member suffers, all the members suffer with it; or if one member is honored, all the members rejoice with it. James 5:16 -Confess your trespasses to one another, and pray for one another, that you may be healed. The effective, fervent prayer of a righteous man avails much. Hebrews 10:24 - And let us consider one another in order to stir up love and good works, There are other examples; these are the first that come to mind.
