Isaiah 27:3 - Exposition

I the Lord do keep it ; or, guard it (comp. Isaiah 26:3 ; Isaiah 42:6 ; Isaiah 49:8 ; Psalms 121:5 ). Vineyards were considered to require special watching, since they were liable to damage both from thieves and foxes (So Isaiah 2:15 ). It was usual to build towers in them, from which a watch could be kept ( Isaiah 5:2 ; Matthew 21:33 ). I will water it every moment (compare the threat in Isaiah 5:6 , "I will command my clouds that they rain no rain upon it"). The Church needs and receives "the continual dew of God's blessing."
