This meditation on the nature of wrath offers two ways of dealing with on an offence. When the speaker is angry with his friend, he told the friend of it and his “wrath did end.” However, when he was angry with his enemy, he kept the anger hidden, allowing it to grow. His wrath, which is watered “in fears” and sunned ‘with smiles, And with soft deceitful wiles,” grows into the poison tree of the title. The tree bears “an apple bright” that the speaker’s enemy desires; the greedy enemy takes the fruit, even though he knows it belongs to the speaker, and eats it. The next morning the speaker is glad to see his “foe outstretch’d beneath the tree.”
