3] Consider Deuteronomy 16:6 (KJV)  

"But at the place which the Eternal thy God shall choose to place his name in, there thou shalt sacrifice the Passover at even (ba erev), at the going down of (when goes down – mss text) the sun (bow shemesh), at the season (ba moet -­ meaning at the season, at the appointed time - refer to spring season, the month of green ears - Abib) that thou camest forth out of Egypt."

Notice there are two distinct terms used in this one verse. We read of at even (ba erev) and at the going down of the sun (bow shemesh).

Both distinct Hebrew phrases are used and each has its own distinct definition and is translated distinctly. One is not a definition of the other.

Should we conclude that the phrase at the going down of the sun is the definition of the Hebrew phrase ba erev?

Did ba erev mean sunset? Clearly not! Bow shemesh is not ba erev.

Bow shemesh is translated here as at the going down of the sun and ba erev is translated as at even. These translations are accurate and definitive.

By reading Deuteronomy 16:6, we understand that the sun had not yet gone down (past tense). We do not read when the sun went down or the sun went down (meaning a process complete, which the Bible uses – we shall read of shortly). Nor do we read that the sun did go down or the sun did set (below the western horizon, implied). Rather we read at the going down of the sun (present tense, the process currently taking place, the process of, implied).

We read of a process or action of the sun. We read that the sun was in the process of going down. It had not reached the exact moment in time of going down (setting or dropping) below the western horizon. We do not read of an exact, moment in time event.

Once again, we read of a process, an action of the sun going down which occurs in the evening time, at even(ing). The sun was in the process of going down – at the going down of the sun. We do not know how high or low or close to the horizon, the sun was. All we can understand is the sun was going down, traveling toward the western horizon. Moreover, we can understand the sun goes down during the evening time. The scriptures confirm this fact.
