Hebrews 3:13

“But exhort one another daily, etc..] In order to prevent unbelief and apostasy. The phrase is sometimes rendered, “comfort one another”, or, “yourselves together”, as in (<520511>1 Thessalonians 5:11) which the saints may do, by discoursing together about divine things; by praying together; by instructing one another in the doctrines of the Gospel; by putting one another in mind of the covenant of grace, and its promises; and by observing the near approach of everlasting happiness with Christ. And though the business of exhortation greatly belongs to ministers of the word, yet it ought not to be neglected by private believers; who ought, when it becomes necessary, to exhort one another to…”

“one another--Greek, "yourselves"; let each exhort himself and his neighbor. daily--Greek, "on each day," or "day by day." while it is called To-day--while the "to-day" lasts (the day of grace, Luk 4:21, before the coming of the day of glory and judgment at Christ's coming, Heb 10:25, Heb 10:37). To-morrow is the day when idle men work, and fools repent. To-morrow is Satan's to-day; he cares not what good resolutions you form, if only you fix them for to-morrow. lest . . . of you--The "you" is emphatic, as distinguished from "your fathers" (Heb 3:9). "That from among you no one (so the Greek order is in some of the oldest manuscripts) be hardened" (Heb 3:8). deceitfulness--causing you to "err…”

“But exhort one another daily - This is addressed to the members of the churches; and it follows, therefore: (1) That it is their duty to exhort their brethren; and, (2) That it is their duty to do it “daily;” that is, constantly; see Hebrews 10:25; 1 Thessalonians 4:18; 1 Thessalonians 5:11; note, Romans 12:8. While this is the special duty of the ministers of the gospel 1 Timothy 6:2; 2 Timothy 4:2; Titus 2:6, Titus 2:15, it is also the duty of all the members of the churches, and a most important, but much-neglected duty. This does not refer to “public” exhortation, which more appropriately pertains to the ministers of the gospel, but to that private watch and care which the individual…”

“But, to prevent it, exhort one another, while it is called To - day - This to - day will not last for ever. The day of life will end soon, and perhaps the day of grace yet sooner. Hebrews 3:14”

“3:13 Using the word “today” from Ps 95:7, the author challenges his hearers to warn each other every day against the deceptive and hardening power of sin.”
