Matthew Poole and continuators on Psalms 83:3

3 They have taken crafty counsel against thy people and consulted against thy hidden ones .

(i. e.) Thy People of Israel, as it is explained in the foregoing words, and in the next Verse; who are called God's hidden or secret ones, to intimate the singular care and respect which God hath to them, as to his peculiar treasure, as they are called Exod. 19. 5. Psal. 135. 4. whom he will hide and preserve in the secret of his presence, and under the shadow of his wings; and withal to note their folly in seeking the destruction of those whom God was ingaged and resolved to protect.
