PSALM 105
The Psalmist magnifies the singular grace of God displayed in selecting and freely adopting one people from amongst all nations of the world. To show that it was not in word only that he had made a covenant with Abraham and his offspring, God did not cease, after having delivered them from Egypt, to confer upon them innumerable benefits; and his design in this was, that those who had been delivered might on their part faithfully keep his covenant, and devote themselves unfeignedly to his service. 1
1 This psalm has no title in the Hebrew or Chaldee, but in the Vulgate, Septuagint, Æthiopic, and Arabic versions, the hallelujah which concludes the preceding psalm is prefixed as the inscription. The first fifteen verses correspond with the first part of a song of thanksgiving, which David composed to be sung after the ark had been brought from Obed-edom to Zion. -- See 1 Chronicles 15:8-22. Hence some conclude, that David was its inspired penman, and that he probably enlarged it at some subsequent period of his history, that it might supply a more complete commemoration of God's signal and extraordinary goodness towards the Israelites from the days of Abraham to their final settlement in the land of Canaan; while others conclude, that it was enlarged by some Hebrew bard, at the restoration of the Jews from the Babylonish captivity. This psalm bears a strong resemblance to the 78th, as well in the subject as in the style, except perhaps that the diction here is rather of a more simple cast.
