1 Kings 20:22

Go, strengthen thyself, and mark, and see, &c. Consider what is necessary for thee to do by way of preparation, and take care that nothing be wanting to oppose the designs of the Syrians against thee, who will certainly return and renew the fight next year. The enemies of the children of God are restless in their malice, and though they may take some breathing-time for themselves, they are still breathing out slaughter against the church: it therefore concerns always to expect our spiritual enemies, and to mark and see what we do.
