וְאִם־בִּ֥ינָה שִׁמְעָה־זֹּ֑את הַ֝אֲזִ֗ינָה לְק֣וֹל מִלָּֽי׃
만일 총명이 있거든 이것을 들으며 내 말소리에 귀를 기울이라
Rashi
Give ear to my words, O Lord when I have strength to ask before You and, when I have no strength to pray before You and the worry is confined to my heart...consider my meditation Heb. בינה. Consider the meditation of my heart. So it is explained in Midrash [Psalms 5:6]: In every [instance of] בינה in Scripture, the accent is under the “nun,” except this one and its fellow (in Job 34: 16): “And if you wish, understand (בִּנָה), hearken to this,” which is not a noun but an expression of “understand,” like (Prov. 23:1): “you should understand well (בין תבין) who is in front of you.” Therefore, the accent is under the “beth.”
