The trees of the Lord are full of sap. 

I will be like the dew to Israel; he shall grow like the lily, and lengthen his roots like Lebanon. His branches shall spread; his beauty shall be like an olive tree, and his fragrance like Lebanon. §  Blessed is the man who trusts in the Lord, and whose hope is the Lord. For he shall be like a tree planted by the waters, which spreads out its roots by the river, and will not fear when heat comes; but its leaf will be green, and will not be anxious in the year of drought, nor will cease from yielding fruit.I, the Lord, have brought down the high tree and exalted the low tree, dried up the green tree and made the dry tree flourish.The righteous shall flourish like a palm tree, he shall grow like a cedar in Lebanon. Those who are planted in the house of the Lord shall flourish in the courts of our God. They shall still bear fruit in old age; they shall be fresh and flourishing.
