Passage, as a verb, means to transit from one place to another. As a noun, it's a place where the going over or across is done. In the Bible, physical passages involved either to simply cross a sovereign territory or private property, or geographical passages over water or through mountainous areas.
During their Wilderness Journey, the Israelites were "headed off at the pass" by the Edomites who refused passage through their territory. It could easily have turned out very differently, but The Lord let the Edomites get away with it.
"And Edom said unto him, Thou shalt not pass by me, lest I come out against thee with the sword."
"And the children of Israel said unto him, We will go by the high way: and if I and my cattle drink of thy water, then I will pay for it: I will only, without doing any thing else, go through on my feet."
"And he said, Thou shalt not go through. And Edom came out against him with much people, and with a strong hand. Thus Edom refused to give Israel passage through his border: wherefore Israel turned away from him." (Numbers 20:18-21 KJV)
Many do not realize that the Israelite promised land was on both sides of The Jordan River. Reuben, Gad and part of Manasseh were given lands east of the Jordan (see Eastern Tribal Lands). In this example, passage was used to describe a ford of the Jordan River.
"And when they came unto the borders of Jordan, that are in The Land Of Canaan, the children of Reuben and the children of Gad and the half tribe of Manasseh built there an altar by Jordan, a great altar to see to."
"And the children of Israel heard say, Behold, the children of Reuben and the children of Gad and the half tribe of Manasseh have built an altar over against the land of Canaan, in the borders of Jordan, at the passage of the children of Israel." (Joshua 22:10-11 KJV)
An opening between rock formations was also a passage, as in this example with the Philistines:
"And the garrison of the Philistines went out to the passage of Michmash."
"Now it came to pass upon a day, that Jonathan the son of Saul said unto the young man that bare his armour, Come, and let us go over to the Philistines' garrison, that is on the other side. But he told not his father."
"And Saul tarried in the uttermost part of Gibeah under a pomegranate tree which is in Migron: and the people that were with him were about six hundred men; And Ahiah, the son of Ahitub, Ichabod's brother, the son of Phinehas, the son of Eli, The Lord's priest in Shiloh, wearing an ephod. And the people knew not that Jonathan was gone. And between the passages, by which Jonathan sought to go over unto the Philistines' garrison, there was a sharp rock on the one side, and a sharp rock on the other side: and the name of the one was Bozez, and the name of the other Seneh." (1 Samuel 13:23-14:4 KJV)
