I think it can be said that different verses can be speaking about multiple things at the same time. Many objects, people, places, etc. in Scripture are themselves the object of the writing, but they themselves also fulfill other roles as, what was pointed out earlier, prefigurements of things to come.
Take for instance Israel. Israel was a man, a nation, God's chosen people from among the nation, and an allegorical reference to the future physical church (of which the OT Israelites who were God's were also a part of).
When it is said that out of Egypt I called my son, this means many things.
Literally, God did call His son, i.e. Israel, out of Egypt, out of the house of slavery. This was immediately applicable to the nation of Israel.
It also applies to God's people, both in the contemporary sense and in the prophetic sense. Certainly when God called Israel out of Egypt, those who were His within the nation of Israel were called out as well. However, this has prophetic prefiguring meaning in that Israel is a representation of God's people after Christ has freed them from the bonds of slavery. Egypt is a representation of slavery, which we as God's chosen Israel have been called forth from through the sacrifice of His Son, Christ.
It also applies to Christ as the Second Adam and His redemptive work on the cross as the Federal Head of God's people, i.e. Israel. Christ has brought us, Israel, out of the house of slavery via His work. In this way, this verse also speaks to this.
As you can see, the verse can mean several different things, at least according to me.
Each meaning is no less valid than the other, but they speak to different objects that have their identity in the name of Israel.
