Matthew Henry Presbyterian @wholebiblehenry

Here we have, I. An account of the restraint laid upon the winds. By these winds we suppose are meant those errors and corruptions in religion which would occasion a great deal of trouble and mischief to the church of God.

Commenting on Revelation 7:1-12

John Gill Reformed Baptist @doctorgill

Of the tribe of Simeon were sealed twelve thousand,.... The name of this tribe signifies "hearing", Gen 29:33; and such an hearing as is attended with obedience; and denotes the spiritual and practical hearing of the Gospel by those who hear, and understand, and believe, and practise what they hear, and yield the obedience of faith unto it.

Geneva Bible Notes Reformed @genevanotes

Of the tribe of Simeon [were] sealed twelve thousand. Of the tribe of Levi [were] sealed twelve thousand. Of the tribe of Issachar [were] sealed twelve thousand. (6) Here the tribe of Levi is listed with the rest, because all the Israelites were equally made priests with them in Christ by his priesthood .
