כִּ֤י אֵ֪ין בְּפִ֡יהוּ נְכוֹנָה֮ קִרְבָּ֪ם הַ֫וּ֥וֹת קֶֽבֶר־פָּת֥וּחַ גְּרוֹנָ֑ם לְ֝שׁוֹנָ֗ם יַחֲלִֽיקוּן׃
For there is no sincerity in their mouth; Their inward part is a yawning gulf, Their throat is an open sepulchre; They make smooth their tongue.
Shaarei Teshuvah
“When you go out to war, etc., and see horses and chariots - forces larger than yours - have no fear of them” (Deuteronomy 20:1). We were warned with this that if a person sees trouble nearby, the salvation of the Lord should be in his heart and he should trust in it - like the matter that is stated (Psalms 85:10), “His salvation is near those who fear Him”; and likewise is it written (Isaiah 51:12), “What ails you that you fear man who must die.”
