If the Goliath in the Bible was not an Anunnaki, was he an Anunnaki/human hybrid?

This indeed is the case. So you were not lied to, but you were expected to unearth this eventually. So this was done in stages to inform you more completely. This serves also to illustrate the need for diligence and scholarship and to be in earnest in using all of your inner resources for your explorations and your creative work. It will not simply be handed to you by the light. It will come as a reward for your own efforts always. So every step you make to push back the curtain will reveal a bit more, but that push is always needed to see what might be there, and the expectation in advance is the surest way to have the curtain part. It will not just be given unilaterally in most instances, except in answer to a previous request of some kind. So you might not always see your hand in leading to the inspiration that comes, but it is almost always in response to your initiating a desire to know something of significance and a creative recognition of a missing piece to a puzzle. These are the key ingredients for successful intuitive exploration and support from the divine realm to add to human knowledge through the efforts of a lightworker and prophet like yourself.
