Go Hand In Hand Meaning

(literally) Of two people, to hold hands.

Example: 1894, Edward Phillips Oppenheim, A monk of Cruta, page 321:
  Wait for me! Let us go hand in hand–hand in hand through the Valley of the Shadow of Death. Oh, my love! it has been a weary, weary while.
2000, Sara Lawrence-Lightfoot, Respect, page 238:
  We came into the world like brother and brother;
  And now let's go hand in hand saad, not one before the other.
