^A “disciples” = mathetes. From matheteuo (to make a disciple of); from manthano (to learn key facts, gain knowledge from experience; generally implies reflection as part of the learning process); from math– (thinking things through). This is a disciple, learner, or student. It is where we get “mathematics” from.
^B “went” = poreuomai. From poros (ford, passageway). This is to go, travel, journey, or die. It refers to transporting things from one place to another and focuses on the personal significance of the destination.
^C “Galilee” = galilaia. From Hebrew galil (cylinder, circuit, district); from galal (to roll in a literal or figurative sense, roll away, roll down, wallow, remove, trust). This is Galilee, meaning perhaps region or cylinder.
^D “Jesus” = iesous. From Hebrew Yehoshua (Joshua, the Lord is salvation); {from YHVH (proper name of the God of Israel; the self-existent and eternal one); {from havah (to become) or from hayah (to come to pass, become, be)} + yasha (to deliver, defend, help, preserve, rescue; properly, to be open, wide or free, which implies being safe. So, in a causative sense, this is to free someone). This is Jesus or Joshua in Greek – the Lord saves or the Lord is salvation.
^E “directed” = tasso. 9x in NT. This word was common in military settings to mean appoint or commission to a certain status. It referred to arranging in a specified order, setting in place, or sending to a specific task.

^F “saw” = horao. To see, perceive, attend to, look upon, experience. Properly, to stare at and so implying clear discernment. This, by extension, would indicate attending to what was seen and learned. This is to see, often with a metaphorical sense. Can include inward spiritual seeing.
^G “worshiped” = proskuneo. From pros (advantageous for, at, to, toward, with) + kuneo (to kiss); {may be related to kuno (dog)}. This is to do reverence, kneel, to prostrate oneself in homage, to worship.
^H “doubted” = distazo. 2x in NT – here and when Jesus walks on water and tells Peter “you of little faith, why did you doubt?” in Matthew 14:31. From dis (twice, utterly, again); {from duo (two, both)} + stasis (standing, place, rebel, insurrection, controversy); {from the base of histemi (to stand, place, establish, appoint, stand ready, be steadfast)}. Properly, this is going back and forth between two stances – wavering or doubting. It can also be used for hesitation.
^I “authority” = exousia. From exesti (to be permitted or lawful); {from ek (out, out of) + eimi (to be, exist)}. This is power to act or weight. It especially denotes moral authority or influence. It can mean domain, liberty, freedom, capacity, mastery, right, force, or strength.
^J “heaven” = ouranos. May be related to oros (mountain, hill) with the notion of height. This is the air, the sky, the atmosphere, and heaven. It is the sky that is visible and the spiritual heaven where God dwells. Heaven implies happiness, power, and eternity.

^K “make disciples” = matheteuo. Related to “disciples” in v16. 4x in NT. From mathetes (see note A above). This is to be or train a disciple.
^L “nations” = ethnos. Probably from etho (a custom or culture). This is people who are united by having similar customs or culture. Generally, it is used to refer to Gentiles. This is a tribe, race, nation, or Gentiles in general. This is where the term “ethnicity” comes from.
^M “baptizing” = baptizo. From bapto (to dip or dye; to entirely cover with liquid, to stain). This is to submerge, wash, or immerse. Used specially for baptism.
^N “name” = onoma. May be from ginosko (know, recognize, learn from firsthand experience). This is a name, authority, cause, character, fame, reputation. The name was thought to include something of the essence of the person so it was not thought to be separate from the person.
^O “Holy” = hagios. From hagnos (holy, sacred, pure ethically, ritually, or ceremonially; prepared for worship, chaste, unadulterated, pure to the core; undefiled by sin; figurative for innocent, modest, perfect). God is totally different from humanity and thus set apart. That which is consecrated to worship God (elements of worship) or to serve God (as the saints) are holy because they are now set apart for God’s purposes. Holy because important to God. This is sacred physically, pure. It can be morally blameless or ceremonially consecrated.
^P “Spirit” = pneuma. From pneo (to blow, breath, breathe hard). This is wind, breath, or ghost. A breeze or a blast or air, a breath. Figuratively used for a spirit, the human soul or part of us that is rational. It is also used supernaturally for angels, demons, God, and the Holy Spirit. This is where pneumonia comes from.

^Q “teaching” = didasko. From dao (learn). This is to teach, direct, instruct, or impart knowledge. In the New Testament, this is almost always used for teaching scripture.
^R “obey” = tereo. From teros (a guard or a watch that guards keep); perhaps related to theoreo (gazing, beholding, experiencing, discerning; looking at something to analyze it and concentrate on what it means; the root of the word “theatre” in that people concentrate on the action of the play to understand its meaning); from theaomai (to behold, look upon, see, contemplate, visit); from thaomai (to gaze at a spectacle; to look at or contemplate as a spectator; to interpret something in efforts to grasp its significance); from theoros (a spectator or envoy). This is to guard, observe, keep, maintain, or preserve. It can also be used figuratively for spiritual watchfulness. It is guarding something from being lost or harmed – keeping an eye on it. Contrast the Greek phulasso, which is to guard something so that it doesn’t escape. Also contrast koustodia, which generally denotes a fortress or military presence. This word can mean fulfilling commands, keeping in custody, or maintaining. It can also figuratively mean to remain unmarried.
^S “commanded” = entellomai. 15x in NT. From en (in, on, at, by, with) + tellomai (to accomplish) {from telos (an end, aim, purpose, completion, end goal, consummation, tax; going through the steps to complete a stage or phase and then moving on to the next one)}.
