No nation has ever experienced the physical wilderness as the nation of Israel. Theirs were the trials, the thirst, the hunger for meat, for the onions and other things Egypt offered. To them were given forty years wandering through the desert for the purpose of being formed as a nation under God Himself. Many died; a large number of them; they did not make it through the wilderness to their destination, because they fell to temptation, while their hearts became hardened as they were tested. The signs and wonders they witnessed when God provided for their needs did not serve as a guide to exercise faith in Him. So their journey became a wilderness of temptation in every aspect: physical, emotional and spiritual. That constituted an open door to fail in every time a need arrived. Without waiting for God to provide for their needs, as He promised He was going to, they murmured and complained, even when manna- food from heaven was given them. They longed the world’s food instead. In Psalm 95 the Psalmist remembers those days with a warning: Harden not your hearts as at Meribah and Massah in the day of temptation in the wilderness, when your fathers tried My patience and tested Me proved Me and saw His work. Forty years long was I grieved and was disgusted with that generation, and I said, It is a people that do err in their hearts, and they do not approve, acknowledge or regard My ways. Therefore I swore in My wrath that they would not enter My rest (95: 8-11), and again in Hebrews 3: 7-11.
Then YAHSHUA, full of and controlled by the Holy Spirit, returned from the Jordan and was led in [by] the [Holy] Spirit for during forty days in the wilderness, where He was tempted by the devil. And He ate nothing during those days, and when they were completed, He was hungry (Like 4:1,2). The devil came to YAHSHUA at the point of His need – hunger. Forty days and nights without eating can starve the body and lead it to death, that is, for some people, depending on their health factors. Forty days is long enough time for the body to have used all the resources it had to be sustained. YAHSHUA, as a man, was subject to the weakness of a human body, but not to man’s sinful nature. He was led to the wilderness by the Holy Spirit to be tempted in preparation for the ministry He was going to fulfill. Like us, He was also subjected to temptations, and to the extent of sufferings that we experience. So after fasting forty days and forty nights, His obvious need of that moment was hunger. Hunger and thirst in the desert are something hard to overcome without having knowledge of how to survive in such environment which lacks everything that benefits the body. The Bible does not say if He went without water however, I assume so. Whatever the situation, He went hungry after forty days.
