'Able' in the Bible

All these [were] the sons of Jediael according to the heads of the {families}, mighty warriors, seventeen thousand two hundred, {able to go to war}.

[They were] armed with [the] bow, [able to shoot] right-handed or left-handed, [slinging] stones or [shooting] arrows with the bow; [they were] kinsmen of Saul from Benjamin.

But David was not able to go before it to seek God, for he was afraid on account of the sword of the angel of Yahweh.
