Intentional hiding

You know some critical information A and B. But you also know if you share both A and B, then that wouldn't fulfill your purpose. So, you decided to only share A and intentionally hide B. Then surely you will accomplish your purpose.

But, be advised. That is making you a liar.
And your becoming a liar not only would give you its consequence, but the whole people would be at stake, as well as God's will.

For those who have no idea about both A and B, then your explanation might be found to be so helpful. Then you might be appreciated as their savior. But be aware that you are fooling the history.

In case if you are so clear about A and no B, then you might regret one day asking yourself why you did not give B a benefit of doubt.
