Be not a witness against thy neighbour without cause; and deceive [not] with thy lips.
Ver. 28. Be not a witness against thy neighbour without cause.] That is, Without calling, being not thereunto required; for this would speak thee spiteful, rash, and revengeful, as in the next verse.
And deceive not with thy lips.] When called to be a witness, speak thy mind simply and plainly, without preface or passion, a without varnish of fine words, whereby to mislead the judge, or deceive the jurors, to bolster out a bad cause, or outface a good.
