Answer:
Do not be influenced by false flattery.
Step-by-step explanation:
This speech is an allusion to the betrayal of Jesus Christ by his disciple Judas on the night of his planned capture. The "Judas' kiss' became a symbol of false flattery and betrayal.
And in reference to the "kiss", Patrick Henry's referring to the British colonizers’ act of making false promises who believe that they are there for the development of the colonies. But contrary to the belief, the colonizers are there to take advantage of their resources and 'siphon off' any valuable resources back to Britain. And considering the circumstance and the Biblical reference, we can interpret the sentence as a warning not to be influenced by false flattery.
