1 Peter 4:7 - Matthew Poole's English Annotations on the Holy Bible

But the end of all things: the last judgment, which will put an end to all the evils as well as good things of this world. Is at hand: see James 5:8,9. Be ye therefore sober; both in mind, prudent, moderate, 2 Corinthians 5:13 Titus 2:6; and in body, temperate in meats and drinks, &c. And watch: the word signifies both sobriety, in opposition to drunkenness, 1 Thessalonians 5:6,8, and watchfulness, 2 Timothy 4:5, and this signification agrees best with this place, the former being implied in the word sober. Unto prayer; the end for which they should be sober and vigilant, viz. that they might observe every season fit for prayer, and might still keep themselves in a praying frame.
