Verse 15: And she said unto him, (Judg. 14:16) How canst thou say, I love thee, when thine heart is not with me? thou hast mocked me these three times, and hast not told me wherein thy great strength lieth.
[When thine heart is not with me] That is to say, thou hast sufficiently demonstrated to me that I am not loved by thee. For whoever truly and sincerely loves, entrusts to the beloved all their secrets (Bonfrerius).
[וְלִבְּךָ] Thine heart, that is, the affection of thine heart, namely, love (Piscator). While thou art of a heart averse to me (Vatablus).
When thine heart is not with me; when thy love consists only in outward expression, not in affection, and thou wilt not open thy heart to me, as one true friend doth to another.
 Hebrew: וַתֹּ֣אמֶר אֵלָ֗יו אֵ֚יךְ תֹּאמַ֣ר אֲהַבְתִּ֔יךְ וְלִבְּךָ֖ אֵ֣ין אִתִּ֑י זֶ֣ה שָׁלֹ֤שׁ פְּעָמִים֙ הֵתַ֣לְתָּ בִּ֔י וְלֹא־הִגַּ֣דְתָּ לִּ֔י בַּמֶּ֖ה כֹּחֲךָ֥ גָדֽוֹל׃
