If any man have an ear, let him hear - See the notes on Revelation 2:7. The idea here is, that what was here said respecting the "beast" was worthy of special attention, as it pertained to most important events in the history of the church.

If any man have an ear, let him hear - These words are evidently introduced to impress the reader with the awfulness of what has just been spoken - all shall worship him whose names are not written in the book of life, as well as to fix his attention upon the following words: -

If any man have an ear, let him hear. And diligently attend to this mystical description of antichrist, as being matter of some difficulty to understand, as well as of great moment and importance, and seriously consider it, that he may know him, and his followers, and avoid them; See Gill on Revelation 1:7.

{14} If any man have an ear, let him hear.

(14) The conclusion of this speech of the first beast, consisting of two parts, an exhortation to attentive audience, in this verse: and a foretelling, which partly contains threatenings against the wicked and partly comfort for those who in patience and faith shall wait for that glorious coming of our Lord and Saviour Christ; Re 13:10

13:9 If any man have an ear, let him hear. Let him give heed. The words to be heeded are in Re 13:10.

9. A general exhortation. Christ's own words of monition calling solemn attention.

13:1-10 The apostle, standing on the shore, saw a savage beast rise out of the sea; a tyrannical, idolatrous, persecuting power, springing up out of the troubles which took place. It was a frightful monster! It appears to mean that worldly, oppressing dominion, which for many ages, even from the times of the Babylonish captivity, had been hostile to the church. The first beast then began to oppress and persecute the righteous for righteousness' sake, but they suffered most under the fourth beast of Daniel, (the Roman empire,) which has afflicted the saints with many cruel persecutions. The source of its power was the dragon. It was set up by the devil, and supported by him. The wounding the head may be the abolishing pagan idolatry; and the healing of the wound, introducing popish idolatry, the same in substance, only in a new dress, but which as effectually answers the devil's design. The world admired its power, policy and success. They paid honour and subjection to the devil and his instruments. It exercised infernal power and policy, requiring men to render that honour to creatures which belongs to God alone. Yet the devil's power and success are limited. Christ has a chosen remnant, redeemed by his blood, recorded in his book, sealed by his Spirit; and though the devil and antichrist may overcome the body, and take away the natural life, they cannot conquer the soul, nor prevail with true believers to forsake their Saviour, and join his enemies. Perseverance in the faith of the gospel and true worship of God, in this great hour of trial and temptation, which would deceive all but the elect, is the character of those registered in the book of life. This powerful motive and encouragement to constancy, is the great design of the whole Revelation.
