טָהֵר

From the study of Proverbs 20:9

Range of meaning

To be clean or pure. It is the technical term for ritual cleanness in the Torah (Lev 11–16), the status that lets a person or object come into contact with holy things. It also covers moral cleansing (Ps 51:4, 9 [Eng 51:2, 7]; Jer 33:8; Ezek 36:25) and the refining of metals (Mal 3:3). The adjective טָהוֹר is used for pure gold and for "pure of heart" (Ps 24:4 uses בַר, but Prov 22:11 has טְהָר־לֵב).

Against the English

Modern English "pure" often means sexual innocence, or a vague sweetness of character. Here it is a status word from the sanctuary: clean enough to approach God.

How it drifted

In modern devotional use "purity" largely shrank to sexual morality. The Hebrew word is about fitness for God's presence, which could be lost through many kinds of contact and wrongdoing.

Used elsewhere in the period

Leviticus 16:30, on the Day of Atonement: "from all your sins (מִכֹּל חַטֹּאתֵיכֶם) you shall be clean (תִּטְהָרוּ) before the LORD." Psalm 51:4 [Eng 51:2] uses the same words as our verse, but as a prayer: וּמֵחַטָּאתִי טַהֲרֵנִי, "and from my sin cleanse me." In Leviticus 13 the priest is the one who declares someone clean (Piel of the same verb).

From the study of Nehemiah 13:22

Range of meaning

To be clean or pure, mostly in the ritual sense: fit to come near holy things. The form here (the 'hithpael', a form that turns the action back on the subject) means 'purify oneself' by washing, waiting out periods of impurity, and avoiding contact with death and similar things (Numbers 8:21; 19). In Ezra–Nehemiah priests and Levites purify themselves before holy service (Ezra 6:20; Nehemiah 12:30).

Against the English

KJV 'cleanse themselves' can sound like ordinary hygiene or a vague moral cleansing. BSB/WEB 'purify themselves' is better but still does not make clear that ritual readiness for holy duty is meant.

How it drifted

Modern readers have no ritual purity system, so 'clean' becomes either physical or simply moral.

Used elsewhere in the period

Nehemiah 12:30 (priests and Levites purify themselves, then the people, gates and wall) is the closest parallel. There the gates of the wall themselves were purified when the wall was dedicated.

From the study of Psalm 51:2

Range of meaning

To be clean or pure, chiefly in the sense of ritual status: fit to enter the sanctuary and take part in worship and community life. The intensive stem (piel) means 'make clean' or 'declare clean'. The priest 'declares him clean' (wəṭihărô hakkōhēn, Lev 13:6, 23). It is also used of refining metal (Mal 3:3) and, by extension, of moral purity (Ezek 36:25, 33).

Against the English

English 'cleanse' sounds hygienic or vaguely moral. The Hebrew carries a formal change of status, from barred to admitted, normally given by a priest's verdict.

How it drifted

Modern readers do not live inside a clean/unclean system. 'Cleanse' therefore shrinks to inner moral improvement and loses the idea of being restored to God's presence.

Used elsewhere in the period

Lev 12-16 (the purity laws); Num 19 (water of purification with hyssop); Ezek 36:25 'I will sprinkle clean water on you and you shall be clean'; Jer 33:8 'I will cleanse them from all their ʿāwōn ... and forgive'. These are the same word pair as here.
