Charles Ellicott Commentary Psalms 83:3

"Thy take crafty counsel against thy people, And consult together against thy hidden ones." — Psalms 83:3 (ASV)

They have taken crafty counsel. — Literally, They have made their plot crafty; or, as we say, “They have laid a deep plot.”

Hidden ones — i.e., those under God’s close protection, as in Psalms 17:8; Psalms 27:5; Psalms 31:20.
