Luke 22:40 Pray that ye enter not into temptation.
Pray not to have [your minds] come into a trial.
In the Greek, the sense is that this is a mental trial because the negative used refers to wanting or thinking something.
The Greek word translated as "pray...ye" means "to offer prayers of vows" either "to worship" or "to ask for a thing". It is a plural command.
There is no "that" here because there because the "enter" verbs is not active.
"Enter" is a word that means "go or come into" and has the double meaning of "coming into one's mind." With the negative used, the sense is clearly "come into your minds".
The negative used here is the Greek negative of a subjective opinion. The sense is that "you don't want" to do something, not that it isn't done or don't think something that might be true. This negative comes before the verb so that it is understood in its sense of "not coming into your minds".
The word translated as "into" means "into" a place, "towards" as a direction, "in regards to" a subject, and "up to" limits in time and measure.
The Greek word translated as "temptation" doesn't primarily means that. It means a "trial" as in a "worry." Christ doesn't use this term but another Greek word to refer to court trials. It could mean a "trial" as a "test." Again, this is an uncommon word in Christ's teaching.
