What does Middle English “bihiȝten” mean?
“And thei herden, and ioyeden, and bihiyten to yyue hym money. And he souyt hou he schulde bitraye hym couenabli.”
King James Bible:
“…And when they heard it, they were glad, and promised to give him money. And he sought how he might conveniently betray him.”
I find that script hard to read so can’t tell about how accurate the ascii is. I searched for a Middle English Dictionary and then tried your text on it and it gave no results. Then I tried other things for the ‘y’ in ‘bihiyten’: ‘h’, ‘th’, ‘g’, and then ‘gh’ which finally worked.
This is plausibly cognate with modern English ‘behest’.
