Psalm 138

“Of David. I will thank thee with all my heart; before the gods I will sing psalms of thee. I will bow down toward the temple of thy holiness and will thank thy name for thy mercy and for thy truth; for above all thy name thou hast magnified thy saying. In the day I called, and thou didst answer me, thou didst encourage me with strength in my soul. All kings of the earth shall thank thee, Jehovah; for (or when) they have heard the sayings of thy mouth. And they shall sing in the ways of Jehovah; for great [is] the glory of Jehovah. For Jehovah [is] exalted, yet he seeth the lowly, and the proud he knoweth from afar. If I walk in the midst of distress, thou wilt revive me; upon the wrath of mine enemies thou wilt stretch forth thy hand, and thy right hand shall save me. Jehovah will perfect as to me: Jehovah, thy mercy [is] forever; forsake not the work of thy hands” (vers. 1-8).
It is Jehovah's faithfulness to His sayings, His mercy in this respect which Israel proved experimentally, and all kings of the earth celebrate in that day. What a change from this day of delusion and infidelity, to which the Jew contributes so largely!
