Joshua and Judges are both important books in the Bible, specifically in the old testament, because they reveal how God delivered the people of Israel from captivities and their conquest of the promised land i.e., the land of Canaan. Joshua is the sixth book of the old testament, and it tells the story of how Joshua after he was chosen by God, led the people of Israel to their promised land.
The stories of how they conquered the land of Canaan, and how they later fought themselves are all in the book of Joshua. Later in this book, the people of Israel were able to turn back to God with the instructions that they should be obedient to the law of Moses. On the other hand, Judges is the seventh book of the old testament, and it tells the stories of how God used some Prophets (judges) to deliver the people of Israel from their enemies.
After their conquest of the promised land, the Israelites would always do things contrary to the will of God, and God would always deliver them to their enemies until they repent.
For those that follow Christianity, they study the words of the holy book the Bible. The Bible has many books in it and two of those books include Joshua and Judges. Both of these books are in the Old Testament of the Bible. They both focus on when the Israelites settled in Cannan.
One difference between them is where they appear in the Bible. The Book of Joshua is the sixth book of the Bible. Judges comes after that, as it is the seventh book of the Bible. Both focus on the settlement, but Judges focuses more on the judges that made decisions and judgement for the people of Israel.
Any serious Christian would know that these terms or names refer to the books of the Bible. The two books are located in the Old Testament, and they both talk more about the settlement of the Israelites in the land Canaan.
The book of Joshua was primarily written in Hebrew language, and it is the sixth book of the Bible, which contains 24 chapters. This book expressly explains the entrance of the Israelites into Canaan Land and their conquest over the land, as well as the division of the land between the Israelites. As earlier said about the location of the book of judges; it is the next book after Joshua and the 7th book of the Bible and Old Testament.
Just as the name implies, this book is more about the biblical judges. The judges then are prophets, they the knowledge of Yahweh and the law, and they make decisions and judgmental for people. The people of Israel were known to be stubborn and sinning against God often, but God uses the judges as leverage towards their sins.
