¹ tc The verb of the first colon is difficult because it does not fit the second very well – a heart does not “scatter” or “spread” knowledge. On the basis of the LXX, C. H. Toy (Proverbs [ICC], 305) suggests a change to יִצְּרוּ (yitsÿru, “they preserve”). The Greek evidence, however, is not strong. For the second line the LXX has “hearts of fools are not safe,” apparently taking לֹא־כֵן (lo’-khen) as “unstable” instead of “not so.” So it seems futile to use the Greek version to modify the first colon to make a better parallel, when the Greek has such a different reading in the second colon anyway.
