just came across this post today and "translated" the commands to Minecraft 1.13.2 (also works with 19w11b) so I could use them:

The next ones need to be used with a command block, since you can't enter as much text as needed in the chat:

/give @p minecraft:diamond_sword{display:{Name:"{\"text\":\"Stabber\"}",Lore:["Way Too Sharp!"]}, Enchantments:[{id:sharpness,lvl:1000},{id:smite,lvl:10},{id:bane_of_arthropods,lvl:10},{id:knockback,lvl:10},{id:fire_aspect,lvl:10},{id:looting,lvl:10},{id:unbreaking,lvl:10}]} 1 /give @p minecraft:diamond_chestplate{display:{Name:"{\"text\":\"Battle Chestplate\"}",Lore:["Soo Much Protection!"]}, Enchantments:[{id:protection,lvl:10},{id:fire_protection,lvl:10},{id:blast_protection,lvl:10},{id:projectile_protection,lvl:10},{id:thorns,lvl:10},{id:unbreaking,lvl:10}]} 1 /give @p minecraft:diamond_leggings{display:{Name:"{\"text\":\"Battle Leggings\"}",Lore:["Soo Much Protection!"]}, Enchantments:[{id:protection,lvl:10},{id:fire_protection,lvl:10},{id:blast_protection,lvl:10},{id:projectile_protection,lvl:10},{id:thorns,lvl:10},{id:unbreaking,lvl:10}]} 1 /give @p minecraft:diamond_boots{display:{Name:"{\"text\":\"Battle Boots\"}",Lore:["Soo Much Protection!"]}, Enchantments:[{id:protection,lvl:10},{id:fire_protection,lvl:10},{id:feather_falling,lvl:10},{id:blast_protection,lvl:10},{id:projectile_protection,lvl:10},{id:depth_strider,lvl:10},{id:thorns,lvl:10},{id:unbreaking,lvl:10}]} 1 /give @p minecraft:diamond_helmet{display:{Name:"{\"text\":\"Battle Leggings\"}",Lore:["Soo Much Protection!"]}, Enchantments:[{id:protection,lvl:10},{id:fire_protection,lvl:10},{id:blast_protection,lvl:10},{id:respiration,lvl:10},{id:projectile_protection,lvl:10},{id:aqua_affinity,lvl:10},{id:thorns,lvl:10},{id:unbreaking,lvl:10}]} 1

Since it's still a lot of work, entering this commands, I've been looking on the internet for other possibilities and found an example of a chest being created with content: (it's in German).

Simply insert this command into a command block to get the chest:

/give @p minecraft:chest{BlockEntityTag:{Items:[{Slot:0b,id:"minecraft:diamond_sword",Count:1b,tag:{display:{Lore:["Way Too Sharp!"],Name:"{\"text\":\"Stabber\"}"},Enchantments:[{lvl:1000,id:"sharpness"},{lvl:10,id:"smite"},{lvl:10,id:"bane_of_arthropods"},{lvl:10,id:"knockback"},{lvl:10,id:"fire_aspect"},{lvl:10,id:"looting"},{lvl:10,id:"unbreaking"},{lvl:1,id:"mending"}]}},{Slot:1b,id:"minecraft:diamond_pickaxe",Count:1b,tag:{display:{Lore:["Pick Your Nose"],Name:"{\"text\":\"Nose Picker\"}"},Enchantments:[{lvl:10,id:"efficiency"},{lvl:10,id:"fortune"},{lvl:10,id:"unbreaking"},{lvl:1,id:"mending"}]}},{Slot:2b,id:"minecraft:diamond_pickaxe",Count:1b,tag:{display:{Lore:["Pick Your Nose Silk Touch"],Name:"{\"text\":\"Nose Picker Silk Touch\"}"},Enchantments:[{lvl:10,id:"efficiency"},{lvl:10,id:"silk_touch"},{lvl:10,id:"unbreaking"},{lvl:1,id:"mending"}]}},{Slot:3b,id:"minecraft:diamond_shovel",Count:1b,tag:{display:{Lore:["Dig This Ya Little!"],Name:"{\"text\":\"Digger\"}"},Enchantments:[{lvl:10,id:"efficiency"},{lvl:10,id:"silk_touch"},{lvl:10,id:"unbreaking"},{lvl:1,id:"mending"}]}},{Slot:4b,id:"minecraft:diamond_axe",Count:1b,tag:{display:{Lore:["Lemme Axe You A Question"],Name:"{\"text\":\"Axe Body Spray\"}"},Enchantments:[{lvl:10,id:"efficiency"},{lvl:10,id:"sharpness"},{lvl:10,id:"fortune"},{lvl:10,id:"unbreaking"},{lvl:1,id:"mending"}]}},{Slot:5b,id:"minecraft:diamond_hoe",Count:1b,tag:{display:{Lore:["Hoe Hoe Hoe, Merry Christmas"],Name:"{\"text\":\"Hoe Hoe Hoe\"}"},Enchantments:[{lvl:10,id:"efficiency"},{lvl:10,id:"silk_touch"},{lvl:10,id:"unbreaking"},{lvl:1,id:"mending"}]}},{Slot:6b,id:"minecraft:fishing_rod",Count:1b,tag:{display:{Lore:["Catch Those Fish!"],Name:"{\"text\":\"Fish!\"}"},Enchantments:[{lvl:10,id:"lure"},{lvl:10,id:"luck_of_the_sea"},{lvl:10,id:"unbreaking"},{lvl:1,id:"mending"}]}},{Slot:7b,id:"minecraft:shears",Count:1b,tag:{display:{Lore:["Cut Your Wool"],Name:"{\"text\":\"Legendary Shears\"}"},Enchantments:[{lvl:10,id:"efficiency"},{lvl:10,id:"silk_touch"},{lvl:10,id:"unbreaking"},{lvl:1,id:"mending"}]}},{Slot:8b,id:"minecraft:bow",Count:1b,tag:{display:{Lore:["I Have Good Aim"],Name:"{\"text\":\"Shooter\"}"},Enchantments:[{lvl:1000,id:"power"},{lvl:10,id:"punch"},{lvl:10,id:"flame"},{lvl:10,id:"infinity"},{lvl:10,id:"unbreaking"},{lvl:1,id:"mending"}]}},{Slot:9b,id:"minecraft:diamond_helmet",Count:1b,tag:{display:{Lore:["Soo Much Protection!"],Name:"{\"text\":\"Battle Leggings\"}"},Enchantments:[{lvl:10,id:"protection"},{lvl:10,id:"fire_protection"},{lvl:10,id:"blast_protection"},{lvl:10,id:"respiration"},{lvl:10,id:"projectile_protection"},{lvl:10,id:"aqua_affinity"},{lvl:10,id:"thorns"},{lvl:10,id:"unbreaking"},{lvl:1,id:"mending"}]}},{Slot:10b,id:"minecraft:diamond_chestplate",Count:1b,tag:{display:{Lore:["Soo Much Protection!"],Name:"{\"text\":\"Battle Chestplate\"}"},Enchantments:[{lvl:10,id:"protection"},{lvl:10,id:"fire_protection"},{lvl:10,id:"blast_protection"},{lvl:10,id:"projectile_protection"},{lvl:10,id:"thorns"},{lvl:10,id:"unbreaking"},{lvl:1,id:"mending"}]}},{Slot:11b,id:"minecraft:diamond_leggings",Count:1b,tag:{display:{Lore:["Soo Much Protection!"],Name:"{\"text\":\"Battle Leggings\"}"},Enchantments:[{lvl:10,id:"protection"},{lvl:10,id:"fire_protection"},{lvl:10,id:"blast_protection"},{lvl:10,id:"projectile_protection"},{lvl:10,id:"thorns"},{lvl:10,id:"unbreaking"},{lvl:1,id:"mending"}]}},{Slot:12b,id:"minecraft:diamond_boots",Count:1b,tag:{display:{Lore:["Soo Much Protection!"],Name:"{\"text\":\"Battle Boots\"}"},Enchantments:[{lvl:10,id:"protection"},{lvl:10,id:"fire_protection"},{lvl:10,id:"feather_falling"},{lvl:10,id:"blast_protection"},{lvl:10,id:"projectile_protection"},{lvl:10,id:"depth_strider"},{lvl:10,id:"thorns"},{lvl:10,id:"unbreaking"},{lvl:1,id:"mending"}]}}],}} 1
