This verb appears in Moses' and Nehemiah's reflections on God's wilderness provision, noting the miracle that Israel's feet did not swell during forty years of desert travel. The term likely refers to blisters, swelling, or edema that would normally afflict feet enduring such constant walking in harsh conditions. This small mercy—healthy feet—stands as tangible evidence of God's comprehensive care, attending to the mundane physical needs alongside spectacular provisions like manna and water from rock.
