Translation of "gesunder Verstand" into English

Von David, als er seinen gesunden Verstand vor Abimẹlech verstellte,+ so daß dieser ihn wegtrieb und er fortging.

Of David, at the time of his disguising his sanity+ before A·bimʹe·lech, so that he drove him out, and he went away.

Nun, da du wieder bei gesundem Verstand bist, wieso wolltest du dich umbringen?

Now that you are of sound mind, Why did you want to kill yourself?
