Let my cry come near before thee, O Lord - This commences a new division of the psalm, indicated by the last letter of the Hebrew alphabet, the letter Tau (ט ṭ), corresponding to our “t,” or “th.” The petition here is, that his prayer might be heard; that it might come into the very presence of God; that there might be no obstructions to its reaching where God was. Let nothing from my unworthiness, from my past sins, from my ignorance, prevent its coming before thee. Something often apparently hinders our prayers so that they do not reach the ear of God. The psalmist prays here that there may be no such hindrance in the prayer which he now offers.
Give me understanding according to thy word - According to the promises of thy word; or, give me the same views of truth which are set forth in thy word. This prayer had been several times offered before, and it shows how earnest was his desire to know the truth. See Psalms 119:34, Psalms 119:73,Psalms 119:144.
