to bring something to true level, as a balance beam or a builder's level does: to grade a path smooth, or to weigh a thing out and size it up
Picture a straight bar that has to come to rest perfectly horizontal before the work counts as finished: the beam of a merchant's scale, or a builder's level. Hebrew had a noun for that instrument (פֶּלֶס), and this verb is what a person does with one. Its core idea is bringing something to true level.
What that comes to in practice depends on what the verb is acting on. The object chooses the sense:
- With a road or a track, the work is grading: take out the dips and clear the way.
- With something handed over, the work is trade: deal it out by weight on the beam.
- With a person's steps under God's eye, the work is appraisal: take the measure of a life.
English keeps those three jobs in separate vocabularies, which is why translators have never settled on one word here. The oldest Greek and Latin translators did not try. They chose a different verb for nearly every verse, saying "make straight" in one place, "scrutinize" in another, "build a road" in a third. Modern versions do much the same. The unity a Hebrew reader felt lives in the picture, not in any single rendering.
The word belongs to elevated poetry and teaching. Four of its six appearances are in Proverbs, and none are in narrative, which suits a book whose governing image is life as a road that either has been prepared or has not. The verb names both halves of that image: what a wise person does about his own path, and what God does about everyone's.
Nuances
Proverbs 5:6: who the subject is (the son or the wayward woman) and whether תְּפַלֵּס means "make level, mark out," "ponder," or "travel upon."
- majorityThe woman is the subject and the verb means marking out or leveling (Waltke: "lest she should make level the path of life"; Clifford: "she does not survey the path"), the reading behind most modern versions. It requires taking פֶּן as an effective negation, a grammatically strained move.; B. K. Waltke, The Book of Proverbs: Chapters 1-15 (NICOT), on 5:6; R. J. Clifford, Proverbs (OTL), on 5:6
- minorityThe son is the subject and the verb means pondering or weighing up: "lest thou shouldest ponder the path of life." This keeps פֶּן in its ordinary sense.; Rashi, Commentary on Proverbs, on 5:6; Ibn Ezra, Commentary on Proverbs, on 5:6
- minorityThe verb denotes movement along a leveled path: "she does not tread the way of life." This is how the Septuagint (ἐπέρχεται) and the Vulgate resolved the line.; A. S. Peake (ed.), Peake's Commentary on the Bible, on Proverbs 5:6
Proverbs 5:21: whether מְפַלֵּס with YHWH as subject means "examines, weighs" a person's tracks or keeps the sense "makes level, ordains" them.
- majority"Examines, weighs, watches": with human conduct as the object the verb shifts to appraisal, as the ancient versions took it (Septuagint σκοπεύει, Vulgate considerat) and as most modern versions render it.; B. K. Waltke, The Book of Proverbs: Chapters 1-15 (NICOT), on 5:21; R. J. Clifford, Proverbs (OTL), on 5:21; BDB, s.v. פלס
- minority"Makes level": the verb keeps one sense across the book, and God smooths or ordains human paths, supported by the parallel claim of Proverbs 16:9 that the LORD directs a person's steps.; M. V. Fox, Proverbs 1-9 (AYB 18A), on 5:21
