Take hold of shield and buckler,.... Defensive weapons; not that the Lord stands in need of any of these to defend himself with: but the sense is, that he would be as these to David; as he was to him, and is to all his people; namely, their shield and buckler: he gives unto them the shield of salvation; he encompasses them about with his favour as with a shield, and keeps them by his power safe from all their enemies; and stand up for mine help; for which the Lord arises, and stands by his people, and against their enemies, delivering them out of their hands.
