כִּי־שֹׁ֭ד יֶהְגֶּ֣ה לִבָּ֑ם וְ֝עָמָ֗ל שִׂפְתֵיהֶ֥ם תְּדַבֵּֽרְנָה׃
因為他們心裡圖謀強暴，嘴裡談論的是禍害。
Rashi
he meditates Heb. יהגה. Every expression of הגה refers to the heart, as you say (below 19:15): “and the meditation (והגיון) of my heart”; (Isa. 33:18), “Your heart shall meditate (יהגה) in fear”; (Prov. 24:2), “For their heart thinks (יהגה) of plunder.”
