Rig Veda 5.78: YE Asvins, hither come to us: Nasatyas, be not disinclined.

YE Asvins, hither come to us: Nasatyas, be not disinclined.
Fly hither like two swans unto the juice we shed.

O Asvins, like a pair of deer, like two wild cattle to the mead:
Fly hither like two swans unto the juice we shed.

O Asvins rich in gifts, accept our sacrifice to prosper it:
Fly hither like two swans unto the juice we shed.

As Atri when descending to the cave called on you loudly like a wailing woman.
Ye came to him, O Asvins, with the freshest and most auspicious fleetness of a falcon.

Tree, part asunder like the side of her who bringeth forth a child.
Ye Asvins, listen to my call: loose Saptavadhri from his bonds.

For Saptavadhri, for the seer affrighted when he wept and waffled,
Ye, Asvins, with your magic powers rent up the tree and shattered it.

Like as the wind on every side ruffles a pool of lotuses,
So stir in thee the babe unborn, so may the ten-month babe descend.

Like as the wind, like as the wood, like as the sea is set astir,
So also, ten-month babe, descend together with the after-birth.

The child who hath for ten months' time been lying in his mother's side,-
May he come forth alive, unharmed, yea, living from the living dame.
