Jerome : (Verse 4) And he measured again a thousand, and he led me through the water up to the knees (or he passed in the water unto the thighs). And he measured a thousand, and he led me through the water up to the loins (or he passed in the water unto the waist). But after one thousand cubits, which bring us to the ankle, he measures another thousand cubits in water and leads me up to the knees. After the forgiveness of sins, and during the journey of progress, when we attempt to ascend even a little from earthly things to higher ones, we bend our knees to the Lord, with the Apostle saying: So that every knee shall bow, in heaven, on earth, and under the earth, and every tongue confess that the Lord Jesus Christ is in the glory of God the Father (Philippians 2:10). He measures another three thousand cubits, and leads me through the water up to my waist, he says. For we climb to lofty heights by degrees: but those very heights descend to the loins and kidneys, so that every base desire within us is cut off; and we possess the sanctification of the body, without which no one sees God. Hence in the same Prophet it is written: 'From His feet to His loins He is a fiery God' (Ezekiel 8:2). For the loins need fire and purgation, as the just man says, 'For my loins are filled with illusions' (Psalms 38:8), through which the enemy deludes us both in the day and in the night time. But from the loins to the head and neck, it shines with the glitter of precious electrum, so that it has nothing filthy in itself, nothing of cheapness. — Commentary on Ezekiel
