Isaiah 32:15 (a) In the days of the tabernacle Moses sprinkled the blood on everything in the tabernacle, and this was a sign to all others that GOD owned these things and had appointed these things for His own purpose and plan. So in the death of CHRIST He is telling us figuratively that in every nation, and among all peoples He will sprinkle the Blood of His Son on hearts and lives to make them His own children, and to save them by His grace.

Ezekiel 36:25 (a) Probably the clean water represents the precious, pure Word of GOD. These pure messages from GOD will be brought to all the peoples of the world in some way or other, and some will believe and be saved. All will be responsible for the way they treat it.

Hebrews 10:22 (b) The teaching in this passage probably is that the Spirit of GOD works through His Word on the heart and the mind of the believer to remove from him the sense of guilt, because the precious Blood of CHRIST has been shed to put away his sins.
