Jews entered the land by miracles

The Bible

For not with their sword did they inherit the land, and their arms did not save them.
(Psalms 44:4)

And I commanded Joshua at that time, saying, “Your eyes have seen all that the L-rd, your G-d, has done to these two kings. So will the L-rd do to all the kingdoms through which you will pass. Do not fear them, for it is the L-rd, your G-d, Who is fighting for you.”
(Deuteronomy 3:21-22)

You shall not be terrified of them, for the L-rd, your G-d, Who is in your midst, is a great and awesome G-d. And the L-rd, your G-d, will drive out those nations from before you, little by little. You will not be able to destroy them quickly, lest the beasts of the field outnumber you. But the L-rd, your G-d, will deliver them to you, and He will confound them with great confusion, until they are destroyed. And He will deliver their kings into your hand, and you will erase their name from beneath the heavens; no man will be able to stand up before you, until you have destroyed them.
(Deuteronomy 7:21-24)

And the people shouted, and (the priests) blew with the trumpets; and it was when the people heard the sound of the trumpet, that the people shouted with a great shout, and the wall fell down in its place and the people went up into the city, every man opposite him, and they took the city.
(Joshua 6:20)

And the L-rd said to Joshua, “Do not fear them, for I have delivered them into your hand; not a man of them shall stand before you.” And Joshua came to them suddenly; he had gone up from Gilgal all night. And the L-rd confused them before Israel, and slew them with a great slaughter at Gibeon, and they chased them by the way that goes up to Beth-horon, and smote them to Azekah, and to Makkedah. And it was as they fled from before Israel, and were in the descent of Beth-horon, that the L-rd cast down great stones from heaven upon them to Azekah, and they died. There were more who died with the hailstones than whom the children of Israel slew with the sword. Then Joshua spoke to the L-rd on the day when the L-rd delivered up the Amorites before the children of Israel, and he said in the sight of Israel, “Sun, stand still upon Gibeon, and Moon in the valley of Ayalon.” And the sun stood still, and the moon stayed, until the people had avenged themselves upon their enemies. Is this not written in the book of Jashar? So the sun stood still in the midst of the heaven, and it did not hasten to go down exactly a whole day. And there was no day like that before it or after it, that the L-rd hearkened to the voice of a man, for the L-rd fought for Israel.
(Joshua 10:8-19)
