Matthew Poole and continuators on Psalms 118:15

15 The voice of rejoycing and salvation is in the tabernacles of the righteous : the right hand of the LORD doth valiantly .

Of rejoycing and thanksgiving for the salvation and deliverance which God hath wrought for me.

Partly because they clearly saw Gods hand in the work, and therefore took pleasure in it: and partly because all good men suffered great inconveniences under Sauls government, as David complains in divers of the foregoing Psalms, and expected and received singular benefits by Davids advancement both in their Civil and Religious concernments.

These are the words of that song of joy and praise now mentioned.
