Observe (4648) (skopeo from skopos = distant mark looked at, goal or end one has in view; English "scope" as in microscope or telescope) means to "spy out", to look at, to observe, to contemplate, to mark ( to fix or trace out the bounds or limits of). Skopeo implies mental consideration and so conveys the picture of attentively fixing one's attention upon something (in this case someone) with desire for (emulation) or interest in. The idea can be to "aim at". Contemplate, look into, examine, inspect, continue to regard closely, to notice carefully, pay attention to, keep one's attention on. Vincent (quoting Schmidt) adds that skopeo means... To direct one’s attention upon a thing, either in order to obtain it, or because one has a peculiar interest in it, or a duty to fulfil toward it. Also to have an eye to with a view of forming a right judgment. There are 6 NT uses of skopeo (mostly by Paul)... Luke 11:35 "Then watch (present imperative) out that the light in you may not be darkness. Romans 16:17 (note) Now I urge you, brethren, keep your eye (present tense = keep keeping your eye on them - this describes a continual need) on those who cause dissensions and hindrances contrary to the teaching which you learned, and turn away from them. 2 Corinthians 4:18 while we look (present tense = habitually) not at the things which are seen, but at the things which are not seen; for the things which are seen are temporal, but the things which are not seen are eternal. Galatians 6:1 Brethren, even if a man is caught in any trespass, you who are spiritual, restore such a one in a spirit of gentleness; each one looking (present tense = continually - almost conveys an imperative sense in this context) to yourself, (Why do you need to continually "mark" yourself?) lest you too be tempted (passive voice = describes temptation coming from outside source). Vincent comments: Notice the passing to the singular number — “considering thyself.” (Ed: = "yourself") The exhortation is addressed to the conscience of each. Before you deal severely with the erring brother, consider your own weakness and susceptibility to temptation, and restore him in view of that fact. (cp 1 Cor 10:12) Philippians 2:4 (note) do not merely look (present tense = continually - almost conveys an imperative sense in this context) out for your own personal interests, but also for the interests of others. Philippians 3:17 (note) Brethren, join in following my example, and observe those who walk according to the pattern you have in us. Paul is commanding (imperative mood) the Philippian saints to continually (present tense) attentively keep fixing their attention upon, (with desire for or interest in) those who exemplify godly conduct. Make it your habit to "scope out" godly examples. Imagine running the 110 meter low hurdles with your eyes on the track or only on the hurdles or constantly on the competition in the lanes on either side. That would be ridiculous. But no more ridiculous than running the race of life (see notes Hebrews 12:1; 12:2) aimlessly as if in a spiritual fog! Only one life. Will soon pass. Only what's done in Christ will last. Run with focus and endurance so at the end of your race you have no regrets... a life well lived for His Name and His glory.
