Leviticus 26:39

בעונת אבתם אתם means if the iniquities of their fathers shall be with them, i. e. if they hold fast to (imitate) the doings of their fathers (cf. Sifra, Bechukotai, Chapter 8 2; Sanhedrin 27b). ימקו — This is an expression denoting “melting away” and therefore means the same as ימסו, “they shall melt away”. Similar to it are (Zechariah 14:12) “[their eyes] shall melt away (תמקנה) in their holes”; (Psalms 38:6) “My wounds נמקו, melt” (i. e. run with pus).

וְהַנִּשְׁאָרִ֣ים בָּכֶ֗ם יִמַּ֙קּוּ֙ בַּֽעֲוֺנָ֔ם בְּאַרְצֹ֖ת אֹיְבֵיכֶ֑ם וְאַ֛ף בַּעֲוֺנֹ֥ת אֲבֹתָ֖ם אִתָּ֥ם יִמָּֽקּוּ׃

And they that are left of you shall pine away in their iniquity in your enemies’ lands; and also in the iniquities of their fathers shall they pine away with them.
