שׁוּבָה יְהֹוָה חַלְּצָה נַפְשִׁי הוֹשִׁיעֵנִי לְמַעַן חַסְדֶּךָ
Return, O Lord, rescue my soul; save me for the sake of Your loving kindness.
The situation is so bad, says king David. I`m so far and detached from You LORD, that there is nothing I can do. Will I try to return to You, will I improve my ways as much as I can – It won`t be enough, even if I will do everything to repent over my sins, the distance is too big.
Therefore, it is up to You! I need You G-d Almighty to return to me. My steps are too small to cover the gap between us – I am dependent on you to bridge the painful situation. (this is king David`s respond to the distance between him and HASHEM described here in Psalm 6:2-5).
We also notice that the request is not because I deserve this to be, rather I ask for Your compassion (Chessed) “for the sake of Your loving kindness“ .
In the next verse, Psalm 6:6, we will see another reason for David to request for HASHEM`s return.
