1 Samuel 2:8

out of the dust "To sit in the dust" (Isaiah 47:1), or "on the dunghill" (Lamentations 4:5) are Oriental figures for a condition of extreme degradation and misery, derived probably from the practice of mourners (Job 2:8): to share the company of princes, and occupy a throne of honour (Job 36:7) are metaphors for advancement and prosperity. Psalms 113:7-9 is copied almost verbatim from these verses. Cp. too Psalms 75:6-7.

for the pillars of the earth are theLord's] The creation and maintenance of the natural framework of the earth by Jehovah are a guarantee for His moral government among men. Cp. Psalms 75:3. The expression "pillars of the earth" (cp. Job 9:6) is a poetical metaphor derived from the construction of a house (see Judges 16:26), and need not imply any theory as to the earth's shape.
