Every believer including the most proficient and seemingly blessed Christians experience times when life becomes in their eyes a giant staring them in the face. And the only reason we ever get to these places is NOT because we lack faith or even power in the Spirit of God!
Let's look into God's word to see just what these giants are...from God's viewpoint instead of from the flesh:
(1.) Heb. nephilim, meaning “violent” or “causing to fall” (Gen_6:4). These were the violent tyrants of those days, those who fell upon others. The word may also be derived from a root signifying “wonder,” and hence “monsters” or “prodigies.” In Num_13:33 this name is given to a Canaanitish tribe, a race of large stature, “the sons of Anak.” The Revised Version, in these passages, simply transliterates the original, and reads “Nephilim.”
(2.) Heb. rephaim, a race of giants (Deu_3:11) who lived on the east of Jordan, from whom was descended. They were probably the original inhabitants of the land before the immigration of the Canaanites. They were conquered by Chedorlaomer (Gen_14:5), and their territories were promised as a possession to Abraham (Gen_15:20). The Anakim, Zuzim, and Emim were branches of this stock.
(4.) Heb. 'emin, a warlike tribe of the ancient Canaanites. They were “great, and many, and tall, as the Anakims” (Gen_14:5; Deu_2:10, Deu_2:11).
(5.) Heb. Zamzummim (q.v.), Deu_2:20 so called by the Amorites.
(6.) Heb. gibbor (Job_16:14), a mighty one, i.e., a champion or hero. In its plural form (gibborim) it is rendered “mighty men” (2 Sam. 23:8-39; 1Ki_1:8; 1 Chr. 11:9-47; 1Ch_29:24.) The band of six hundred whom David gathered around him when he was a fugitive were so designated. They were divided into three divisions of two hundred each, and thirty divisions of twenty each. The captains of the thirty divisions were called “the thirty,” the captains of the two hundred “the three,” and the captain over the whole was called “chief among the captains” (2Sa_23:8). The sons born of the marriages mentioned in Gen_6:4 are also called by this Hebrew name.
Beloved, the eighth and youngest son of Jesse, a citizen of Bethlehem. His father seems to have been a man in humble life. His mother's name is not recorded. Some think she was the Nahash of 2Sa_17:25. As to his personal appearance, we only know that he was red-haired, with beautiful eyes and a fair face (1Sa_16:12; 1Sa_17:42).
His early occupation was that of tending his father's sheep on the uplands of Judah. From what we know of his after history, doubtless he frequently beguiled his time, when thus engaged, with his shepherd's flute, while he drank in the many lessons taught him by the varied scenes spread around him. His first recorded exploits were his encounters with the wild beasts of the field. He mentions that with his own unaided hand he slew a lion and also a bear, when they came out against his flock, beating them to death in open conflict with his club (1Sa_17:34, 1Sa_17:35).
While David, in the freshness of ruddy youth, was thus engaged with his flocks, Samuel paid an unexpected visit to Bethlehem, having been guided thither by divine direction (1Sa_16:1-13). There he offered up sacrifice, and called the elders of Israel and Jesse's family to the sacrificial meal.
