Forbids who from lying? Can you provide book Chapter and verse that say He/God is not able to lie?

You know, when I saw this I immediately thought of Hebrews 6:18 ("it is impossible for God to lie") but the context implies, not that god cannot ever lie, but that when he swears an oath he can be trusted to keep it.

Hebrews 6:16 People swear by someone greater than themselves, and the oath confirms what is said and puts an end to all argument. 17 Because God wanted to make the unchanging nature of his purpose very clear to the heirs of what was promised, he confirmed it with an oath. 18 God did this so that, by two unchangeable things in which it is impossible for God to lie, we who have fled to take hold of the hope set before us may be greatly encouraged. 19 We have this hope as an anchor for the soul, firm and secure.

I read the "two unchanging natures" to refer to his purpose and his oath. Although why a being with an unchanging purpose would need to swear an oath is beyond me. But there does not seem to be any scripture that says that god cannot lie, and this scripture would imply that he is quite able to, barring those times when he swears an oath or if a lie would run contrary to his purpose. I admit I find it pretty fascinating.
