Pillar verses (1 Samuel 2:8, Job 26:10, Psalm 75:3) are all in poetic contexts. In 1 Samuel 2:8, "pillars of the earth" are leaders whom God exalts — the context is about God raising the poor to sit with princes. In Psalm 75:3, pillars are leaders God supports during upheaval. "Pillars of heaven" (Job 26) may just refer to mountains poetically.

1 Samuel 2:8: context is God exalting the poor; "pillars" = leaders he establishes. Psalm 75: pillars = leaders God steadies during turmoil; "earth" = people groups. Job 26: poetic book using poetic language; "pillars of heaven" likely = mountains. Every occurrence of cosmological "pillars" appears in highly poetic contexts.
