A. Working together for a common goal:

2KI 10:15. And when he was departed thence, he lighted on Jehonadab the son of Rechab coming to meet him: and he saluted him, and said to him, Is thine heart right, as my heart is with thy heart? And Jehonadab answered, It is. If it be, give me thine hand. And he gave him his hand; and he took him up to him into the chariot.

AMO 3:3. Can two walk together, except they be agreed?

PHI 1:27. Only let your conversation be as it becometh the gospel of Christ: that whether I come and see you, or else be absent, I may hear of your affairs, that ye stand fast in one spirit, with one mind striving together for the faith of the gospel;

ECC 4:10. For if they fall, the one will lift up his fellow: but woe to him that is alone when he falleth; for he hath not another to help him up.

1SAM 14:6. And Jonathan said to the young man that bare his armour, Come, and let us go over unto the garrison of these uncircumcised: it may be that the LORD will work for us: for there is no restraint to the LORD to save by many or by few.

1SAM 14:7. And his armourbearer said unto him, Do all that is in thine heart: turn thee; behold, I am with thee according to thy heart.

NEH 4:16. And it came to pass from that time forth, that the half of my servants wrought in the work, and the other half of them held both the spears, the shields, and the bows, and the habergeons; and the rulers were behind all the house of Judah.

NEH 4:17. They which builded on the wall, and they that bare burdens, with those that laded, every one with one of his hands wrought in the work, and with the other hand held a weapon.
