Luke 20:20

And they watched him, and sent forth spies, which should feign themselves just men, that they might take hold of his words, that so they might deliver him unto the power and authority of the governor.

They watched him, and sent out spies, who pretended to be righteous, that they might trap him in something he said, so as to deliver him up to the power and authority of the governor.

And they watched him, and sent forth spies, who feigned themselves to be righteous, that they might take hold of his speech, so as to deliver him up to the rule and to the authority of the governor.

And, having watched `him', they sent forth liers in wait, feigning themselves to be righteous, that they might take hold of his word, to deliver him up to the rule and to the authority of the governor,

So they watched Him closely and sent spies who pretended to be sincere. They were hoping to catch Him in His words in order to hand Him over to the rule and authority of the governor.
