βλέπετε [46 verses](2nd pl pres imperat act) "Take ye heed" is blepo, which means "to look" and "to see." It is the more tangible sense of seeing, such as seeing what is right in front of you rather than understanding.

KJV — word by word

Take -- (WW) -- The verb translated as "take heed" means "to see", "to look to", "to look like", "to beware", and "to look for." It is the more tangible sense of seeing, such as seeing what is right in front of you rather than understanding "look" in English. The sense is English is "look out!" or "watch out!"

ye -- (CW) -- This is from the second-person, plural form of the following verb. However, using it makes the verb sound less like an imperative command.

heed, -- There is no noun here. This comes from the previous verb, which just means "see."

watch -- (WW, WT) "Watch" is a verb that Jesus only uses twice that means "to lie awake", "to pass sleepless night," and "to suffer from insomnia."

and pray: -- (OS) There are no Greek words that can be translated as "and pray" in the source we use today but it does exist in the source that the KJV translators used.

for --The word translated as "for" introduces a reason or explanation so "because" and, in questions, "why." However, since this word always appears in the second position, it is more like an aside remark like, "consequently" or "as a cause". 

ye -- This is from the second-person, plural form of the following verb.

know --- The word translated as "know" means primarily "to see" and is used to mean "know' as we use the word "see" to mean "know" in English. It is the past perfect tense so "have seen" but it is translated as the present tense of "know."  What someone "has seen" is what they "know" in the present. Since the past perfect of "see" forms the present tense of "know" the pluperfect tense used here, which indicates an action completed before some other action in the past, is used as the simple past tense, "knew." 

not -- The Greek word translated as "not" is the Greek negative used to deny objective facts, not opinions. It makes a negative statement of fact. Adding "really" to the sentence captures the same idea. When a negative precedes the verb, it affects the whole clause. When it precedes other words, its force is limited to those words.

when  -- The Greek word for "then" means "at this time" or "then". 

the -- The word translated as "the" is the Greek definite article, which usually precedes a noun and, without a noun, takes the meaning of "the one." The Greek article is much closer to our demonstrative pronouns ("this", "that", "these", "those"). See this article for more. 

time  -- (CW)  "The time" is a noun that means "due measure", "season", "opportunity", "time," and "profit." This is not the word usually translated as "time."

is. -- The verb "is" here is the common form of "to be" in Greek. It means to have a certain characteristic or remain in a certain condition. It also equates terms or assigns characteristics. -- When the verb "to be" appears early in the clause before the subject, the sense is more like "it is" or, in the plural, "there are."
