'Command' in the Bible

Then Samuel said to Saul, "You have behaved foolishly! You have not kept the command of Yahweh your God which he commanded you. For then, Yahweh would have established your kingdom over Israel forever.

Then Saul and all the troops who were with him were assembled on command and came up to the battle, and look! Each [Philistine's] sword [was] against his friend; [and there was] a very great confusion.

Please, let our lord command your servants [who are] before you! Let them seek a man skilled in playing on the lyre. {When} the evil spirit from God [is] upon you, he can play {on it} and {you will feel better}."
