· An emblematical proverb, which means that Jahve is for the heart what the smelting-pot (from צָרַף, to change, particularly to melt, to refine) is for silver, and what the smelting furnace (כוּר, from כּוּר, R. כר, to round, Exo_22:20) is for gold, that Jahve is for the heart, viz., a trier (בחן, to grind, to try by grinding, here as at Psa_7:10) of their nature and their contents, for which, of the proof of metals, is elsewhere (Pro_16:2; Pro_21:2; Pro_24:12) used the word (cf. בְּחוֹן, the essay-master, Jer_6:7) תֹּכֵן, weigher, or דּוֹרֵשׁ, searcher (1Ch_28:9).
